Realme 5 Pro has a major power consumption problem - background apps drain battery a lot [RAWDUMP]

As can be seen in the screenshots below, sometimes apps that you aren't even using end up wasting hundreds or even thousands of mAh of the phone's battery. Power usage statistics show that it's the background usage that's the culprit. Happens randomly - Flipkart never did this earlier. In contrast, the same apps don't exhibit the same energy-draining behavior on my Xiaomi Poco F1, implying that the apps themselves might not be responsible. In any case, the problem is severe enough that Realme is off from my future phone purchases.






The problem now - Sep'20 - is serious enough that Realme as a brand for future smartphone purchases / recommendations will have to be blacklisted until this issue is resolved fully. Look at the mess with Douyin.


And now the tolerance lines are being crossed. A supposedly dumb app such as Photos is draining huge amounts of battery.


The problem is totally out of hand. Installed a game yesterday, and see how it's gobbling my battery in just one day with zero usage today. Horrible for Realme.


More nonsense. A simple third-party camera app is eating energy like anything.

Deodorants or other consumer products containing alcohol can be used as disinfectants or sanitizers in emergency [COMPACTIDEA]

Of course, what percentage/proportion of the product is alcohol matters. Deodorants marketed as "gas-free" are particularly strong [more potent than sanitizers sold at medicine shops].

A bouquet of thoughts related to India's ban on 59 Chinese apps, Huawei, Indian relations with Russia and the US, etc. [RAWDUMP]

  • HELPING MUKESH AMBANI / RELIANCE: Modi government has used the border clash with China as a clever pretext to quickly execute those steps which appear to the public as necessary/valid anti-China measures, but are in reality designed to help Mukesh Ambani's current or upcoming business needs.
    • Retail efforts help.
      • Ban on Club Factory + Shein. [link 1]
  • LOSS TO INDIA OF HEDGE / DIVERSITY / OVERDEPENDENCE: Before Chinese digital apps/services provided a healthy hedge against overdependence on Western commerce and social media services, India had been overly dependent on Western - particularly American - services. Chinese giants such as TikTok, WeChat, Xiaomi [apps], Alibaba, etc., provided not just healthy market competition to US apps, but also reduced India's dependence on a single country/bloc. That hedge evaporated with Modi's ban-after-ban on hundreds of Chinese apps.
    • Indian apps market is now almost monopolized by giant American corporations.

Following photos show not just the crushing and worrying dominance of American apps, how also how non-US/non-Western apps - in this case TikTok, Snack Video, Telegram, and to an extent Zoom - provide not just healthy market competition to the dominant giants, but also diversify a country's digital cyberspace, reduce overdependence.

  • Taiwan to block streaming services of Tencent and Baidu's iQiyi
  • India banning Huawei will hurt Airtel, Vodafone Idea, help Jio
  • Reliance tech arm expands monopoly muscle in India

Desperately hoping to see world's fastest supercomputer coming out from China based on Huawei's flagship Kirin or Kunpeng processors [COMPACTIDEA]

America is creating way too many hurdles for Huawei. Way too many. A tight slap on the face of America is warranted. What better way than to support Huawei by using its flagship Kunpeng and/or Kirin microprocessors to build China's next supercomputer, and build it such that it's all of these - the most powerful in the world, easy to program, highly energy efficient, having no American hardware, and heavily advertise it as having been put to use for nuclear weapons simulations + medical research + weather modelling [to tease/threaten/unsettle the Americans]. That would be a lesson that America won't forget.

Dedicated monochrome cameras and air purifiers - unnecessarily exorbitantly priced products that can be implemented for much lower price

Particularly true for dedicated black-and-white [grayscale] cameras. Despite the basic premise being so simple - the use of a monochrome sensor rather than a color sensor - the models available on the market are all horribly expensive, whereas the regular, colored cameras start at throwaway prices. It isn't like monochrome sensors are costly - several Huawei / Honor smartphones over the years have incorporated a monochrome sensor as part of the multi-camera setup. The real reason seems to be companies' desire to milk people as much as they can. Same with dedicated air-purifiers. Regular ACs installed in homes already have almost all the components that comprise an air-purifier - motors, casing / housing, control board, wiring, fans, etc. The only thing that needs adding is fortification of the dust filter inbuilt into the air conditioners. The basic point here is that at least for some products, prices are unnecessarily high, when the core feature / functionality of those products can be implemented for a much cheaper price.

What will happen to Huawei, MediaTek, Samsung, etc., if Qualcomm acquires Arm Holdings [COMPACTIDEA]

The ARM-based chip businesses of these Qualcomm rivals could get in jeopardy overnight if Qualcomm one day acquires Arm Holdings. This is not a small risk. License fees could go up dramatically. Latest designs could be given late. And so on. This is a threat that the likes of Huawei must not forget - not now after all that's being done to Huawei these days. Makes it all the more vital that Huawei and others start nurturing RISC-V chips immediately, as a solid future hedge against any kind of sanctions, blacklisting, takeover or other political restrictions. Owning the complete stack, and especially those vital parts which are ultimately under the control/ownership of hostile nations such as US and UK is critical for survival and growth.

Some quick improvements needed to Xiaomi Mi security camera to make it much more useful [RAWDUMP]

It's when you start using a product that you quickly begin to see its shortcomings / areas of improvement:
  • Camera can be rotated along 2 axes, but you can't create a bookmark of select positions. Each time you want to see something to, say, top-right, you have to repeatedly press the movement buttons to get there. Should be possible to create bookmarks that record positions of each axis.
  • To scare those being observed [e.g., factory workers], that you're being watched, camera should sometimes randomly rotate, giving the appearance that 'something is going on'.
  • Similarly, the various colored LED lights on the camera should sometimes blink in random ways to give the appearance that 'your boss is watching'.

Improvements needed in Amazon Fire TV Stick 4K which will make it a much more useful device [RAWDUMP]

    • Anywhere where you can / have to type, should be possible to voice dictate it using Alexa, the way one can voice dictate anywhere in Android using Google. At times you need to type a lot and it's very difficult using the supplied remote controller.
    • If you speak "Baghdad 1968", Alexa types that as "Baghdad nineteen sixty eight". Not right. Search results in both YouTube and the browser go bad as a result.
    • When you do an Alexa search, it should return results from inside the respective content libraries of all the apps that you've installed. For example, when I do a search for some movies, those aren't returned in the results even if an app, say JioCinema, has those for free viewing. Each app's database needs to be indexed.
      • Of course, Amazon probably wants you to view stuff only on its own Prime app.
    • Not possible to pass on the spoken search query to the installed Mozilla Firefox browser - can pass it only to YouTube, Amazon Silk, or Amazon Music. Probably a deliberate choice to cripple Firefox and to direct users to Silk.
    • Some queries that you speak to Alexa, you intend to search for those on the Web, by passing the query text to Silk's default search engine. But many times, Alexa gives a sort of "answer" to that query. For example, if you speak "latest news", Alexa starts the NDTV latest news video, but there's no way to pass the text "latest news" as a text search query to Silk's default browser. Another similar query is "Disha Patani age", for which Alexa forcibly gives you a direct answer without converting the voice query to text.
    • Several voice searches Alexa just doesn't transcribe to text form, no matter how clearly/slowly you speak, and even if those queries seem pretty simple [Alexa just says "sorry...", and doesn't even provide any sort of 'instant answer' to that query]. For example, as of Nov'19, if you speak "Hyundai Venue", intending to pass on the transcribed text as a Web search to Silk, Alexa simply returns a 'sorry' message and doesn't transcribe it. Quite frustrating, since this happens with several queries.
    • Silk is a good browser, but having to move the on-screen cursor / pointer all the way up or down in order to scroll a webpage up or down is tiresome. Dedicated scroll-up and scroll-down buttons needed on the remote, and this'll make Web browsing much better.
    • Allow inserting a microSD card, say a cheap 128 GB card, to act like a disposable cache. Songs that you frequently play, movies / videos that you watch repeatedly, etc., will be cached locally to reduce server load, to save user's data usage, and to increase responsiveness. Even an ongoing movie should be fully cached to the extent it has been played, so that if you go back to any previous scene, it plays instantly.
    • Processor should be faster. Compared to contemporary mid-range smartphones, even the latest 4K model of Fire TV Stick feels just a bit sluggish and jerky at times [this is more pronounced in the inbuilt Firefox, but also with Silk when the webpage in question is complex/heavy].
    • Firefox-specific
      • Default up-down scrolling speed in the inbuilt Firefox browser should be faster.

ActiveX plugin - Java applets and JavaFX - Flash Player and ActionScript - Silverlight .NET - Native Client NaCl and PNaCl - asm.js - WebAssembly Wasm - Bytecode Alliance

What the hell is going on here? So many technologies over the years but still no widespread use of native code / binary code / bytecode in Web browsers in 2019? It seems like the situation was much better several years ago, when, despite security issues, the use of ActiveX, Java / JRE and Flash Player plugins was widespread. In particular, the latter two had near ubiquitous penetration on desktop systems. And it wasn't just the install base of these browser plugins - you would routinely come across tiny applications, games, puzzles, riddles, animations, and other useful stuff within webpages, executed using these platforms. Not any more. In a way, despite us having rich Internet applications [RIAs] such as Gmail, that run inside a Web browser, we've lost out on those tiny little applets which used to run within Web pages and were a lot of fun [not to mention useful].

Perhaps some parallels can be drawn between this, and the Russian approach to their rockets - Proton and Soyuz. The Russian approach has been to continue to evolve and refine the same basic decades-old designs - adding new technologies, optimizing components, making refinements, and so on. No doubt this approach eliminates the possibility of a fundamentally new design from scratch, but it does have the benefits of a product whose troubles have been sorted out, which has been optimized to its theoretical limits, and which has superb reliability and availability, backed by decades of practical experience. In any case, having something that works nicely - even if somewhat inefficiently - is better than having nothing at all. The point here is what's the use of creating technology after technology for native code inside browsers if you aren't going to commit to any one and bring useful products to the users? ActiveX, for example, could've been and should've been evolved and refined to solve its security issues [sandboxing, for example], instead of abandoning it altogether.

Kartarpur Corridor will probably be misused by Pakistan to fuel Sikh separatism in Punjab - specifically the creation of Khalistan

It's no secret that a section of Sikhs has been trying for decades to carve out the so-called Khalistan from the Punjab state of India. Despite violent events lasting years, this sentiment hasn't died down fully, and continues to smolder, and take form and shape in both India and abroad. It has been said that Pakistan has been providing help to these separatists both to harm India in general, and specifically as a payback for India's carving out Bangladesh from East Pakistan. In this context, opening of the Kartarpur Corridor should be a serious cause of concern for India's sovereignty - not for the visa-free pilgrimage itself, but for how under the guise of a holy visit, the separatist elements can secretly meet with and conspire with Pakistani agents, the ISI, Pakistani government, etc., completely out of the watch of Indian government and Indian intelligence. Free from the Indian scanner, conspiracies can be made regarding provision of funds, weapons, etc., and strategic long-term plans can be made regarding how to convert the prosperous Punjab state into a new Sikh nation - Khalistan. What stops the separatist folks visiting Pakistan as pilgrims from venturing out of the holy sites and on to the streets of Pakistan, to conduct secret meetings with anti-India elements there?

One quick though partial solution to this issue can be this - contractually require that any convoy of pilgrims visiting the shrine be accompanied by a handful of Indian security personnel. Package/sell this as needed for the safety/security of the visitors themselves, but the private Indian motive should be to keep a watch for any suspicious activities by Pakistan, such as contacting any of the pilgrims, or passing of any type of information or packages, etc.

Update [28-Dec-19]: Looks like there is a hurricane of funding coming to this program from wealthy Sikhs all over the world. Peter Virdee is just one example. The impact, thus, will be much larger now.
