The battery of my good old Huawei Y300 is slowly dying. So I thought it was time to cut the battery consumption a little. What a delusion. A new battery costs < $5 btw, but I'm too lazy to order :)

I've tested 16 highly acclaimed (of about 20,000, didn't count all of them) battery apps - they're all!, and I mean all!, total crap. There is not a single app that does what it promises. And all totally fucked up with advertising - including some of the paid apps. Most apps consume more power than they actually save.

The winner of all this shit was the app "Battery Repair", which supposedly repairs broken cells. Well, well.

All that junk should be thrown out of the store. But, no, these crap apps have ratings of 4.5 - 4.8 with millions of downloads. I don't get it.

The only app that actually works is, hard to believe, Kaspersky Battery Saver.

So if someone else wants to "optimize" their battery - forget it, it's not even worth looking for it.

Just wanted to clean up and update my old smartphone (Huawei Y300). Accidentally deleted the home screen and system.ui and can no longer open apps. TRWP (2.5.x) is too old to flash a new image. Need TRWP 2.6.3.3, but it is impossible to update it from within TRWP. Such a crap.
