Well I think I figured out a way to make my Boyue T62+'s battery last waaay longer!

In the past few months that I've been using and enjoying this nice device, one thing became obvious: There seems to be a bug in the OS that's triggered later by installing apps and this bug causes the device's battery drainage rate to go much higher and go down faster when it's actually in "Sleep Mode" and is supposed to not do anything important!

Although I haven't got much free time to spend on finding the root of this problem but I've been investigating the cause for some time without any success. It was obvious though that the device's battery usage rate is much higher when it's not ON or completely OFF but in "SLEEP" mode!

So I got this idea to activate this feature in "Better Battery Stats" (BBS) app for "Active Monitoring" which is supposed to monitor the device's activity 'actively' by waking it up for a few seconds every hour, create a log of the situation, and go back to sleep.

After activating this I started to notice that the battery drainage rate while the device was in Sleep mode, went from like 2%+ per hour to 0.05% per hour! So after a few days I went in BBS' settings and changed the frequency of waking the device up for that "Active Monitoring" thing from every 1 hour to every half an hour and this resulted in an even lower battery drainage rate of around 0.03% on average!

As you might have noticed on these devices, when you fully charge them to a 100% until the green LED turns off (which means the battery is fully charged) the battery level shown inside the OS stays at 100% for hours and then starts to go down relatively fast. After activating this and after a full charge, the device's battery level remained on 100% for the first 3 days!

Now more than 7 days have passed since I fully charged it and I've used the device for more than 10 hours with a few hours of WiFi and Front-light and even audio output, and there's still 22% of the battery left. The device was giving me at most 1.5 days with the same usage hours before which was awful and I had to recharge it every day or two! [I did turn the "active monitoring" thing off for about 6 hours once during these past 7 days which resulted in almost 10% of fast battery drainage while the device was in Sleep! If I hadn't done that, it would've probably been at 32% now instead!]

Here's some info about my device, the ROM currently on it, and the apps I have installed (both active and inactive/disabled) in case you wanna compare:

Spoiler:

Also I did this thing a while ago using a feature in the app "ES Task Manager" called "Startup Manager" to prevent any app that I don't need, from occupying RAM space after every time I turn the device ON (either from Sleep or Off state) and by doing this I've got more free RAM space and the device and apps run more smoothly and much faster cuz there's more free RAM available at any moment:

Hope these work on your devices, too, to get more battery life out of them. Also notice that you might need to root your device for some of these apps/features to work.
