Rooted Kindle 7 Battery Life - Fire HD 6 and 7 Q&A, Help & Troubleshooting

Can anyone offer any advice for helping the battery life on the device? I have some terrible battery drain even when I put the device to sleep? I have greenify and Amplify loaded on my device, but it still seems to lose a good bit of battery when not in use.

Battery Problem

I have flashed over 5 roms now and the biggest problem i'm seeing is that the battery drains really fast on the wm 6.5 roms. I was wondering if there is a way to prevent this problem or a way that can help reduce this problem?? Thank you!
I think battery drain is relative to user's opinion. Some might say 2 days of battery life is not enough, and some other might say one full day battery life is normal.
There are many ways to minimize battery consumption. Minimal battery consumption means longer battery life. You may try WMLongLife (adds little bit more battery life, in my device). There's also a thread about battery life tips floating in this forum. I forgot who wrote it. It's a very well-written thread. You may search for it.

[Q] Vibrant - Gummy - Battery Life

Hi,
I installed Gummy 1.2.0 on my vibrant. The first day or two I was getting amazing battery life. For instance with light-medium use, 30% of the battery was gone in 12+ hours, I was amazed. When I was getting this type of battery life Android system was using about 6-7%.
I noticed that as time passed, the battery life started getting worse and worse. I noticed that the Android System was eating up more and more battery even when it was supposed to be in deep sleep. Now Android System is using almost 40%
Has anyone else had the same experience? Great battery life changing to mediocre battery life in a couple of days.
Please advise.
Thanks!!!
I suggest you get Betterbatterystats and that way you can see exactly what is causing the problem. It is available in the market, but there is a free version here in post 2. IIRC the AOS taking so much of your battery life is bc of some errant process that is constantly drawing/polling on the system and causing the dismally high % of use. Find the app, fix it and your problem will be solved.

The note has terrible battery life in general. However Beanstalk has pretty decent battery life relative to other roms. Some things you can do to track your battery life is get BetterBatteryStats from the playstore and see if there is an app or service that is draining your battery.
You might want to try a battery saver app?
I can recommend you try turning off sync option as there maybe apps that push (or even worse pull) too often causing a huge battery drain as well. I recommend only trying that to see which apps cause a battery drain if that is the case.

Good Battery Life on Lollipop? (Stock based rom)

Sort of a general question, but I'm wondering, has anyone been able to achieve good battery life on a stock based rom? (Jasmine, Skydragon etc). I love the LG camera, so I've been sticking with stock based roms, but I've tried everything imagineable to try and save battery on this phone and I can't seem to do it. The best I've been able to get out of this phone is right under 4 hours of screen time and I'm losing about 2.5% every hour when the screen is off. Wakelocks and other battery monitors don't really show anything crazy going on that I can tell, but the culprit seems to be Android OS (as usual).
I've heard of lowering the resolution saving some juice, but I'd rather not do that if I didn't have to. I've got greenify, amplify and other minor tweaks running. Anyone been able to find a real way to increase battery life on this phone? I'm tempted to get a new phone if I can't fix the issue. My old S4 used to get 6+ hours of screen time easily.
try downloading jasmine lollipop with xposed using greenify module. use STOCK kernel. ive seen better battery using the stock kernel than using skydragons. delete amplify because ive found that it drains battery rather than saving it. buy greenify if you have a little cash. and greenify some system apps. I sometimes get 5 and a half hours sot.

Smartswitch Option Missing?

Hello
I've recently been experiencing some very power battery life, losing like 11% during the night without touching the phone, so I have looking for solutions and none of them are working, I installed Gsam and it shows that "WIFI Active" drains a lot of battery and my device is held awake for like 1hr25mins through the night, that is without touching it in 4hrs. Tell me if this is normal or i'm just freaking out but I feel like it shouldn't be held awake for that long. Anyway I used to get pretty good battery life like 1 day and around 5hrs SOT, with some optimizations managed to get 9hrs of SOT with just less than a day of battery life,... but after the recent two updates U2COIK and now U3QOJ5, things have been really bad. Now since I saw WIFI sucking the most I decided to change some settings, but noticed something weird with this build I can't find "SmartSwitch" setting under WIFI like I had before, which has led me to think that it might be on by default and sucking my battery... does anyway with the build i have still have the SmartSwitch feature?? And any help with regaining my good battery life would be much appreciated, just not yet ready to trip my Knox.
Thank you
