[Q] Any way to Increase battery life?

I'm just wondering if there's any known methods to increase the battery life without sacrificing performance. I know the basic stuff like turning off Gps, Wifi, Data, etc. when not needed but is there anything else I can do to prolong the battery life? I'm currently running the wanam lite rom with trininty's alpha 7b kernel. A couple of people reported great battery life with this combo but I'm only getting a little bit better than stock battery life.

What exactly is a little bit better than stock? How many hours are you getting?

Well with moderate use ( 3-4 hours of web browsing, playing games, etc.) on stock I get about 9 hours and with this rom and kernel I get roughly 9 and half.

I get the same too, kind of hate it :/ I don't understand what drain so much when the phone is not in use, I always wonder why stand by time is so bad in my phone, I get much better battery life rooted but I'm stock right now, I got tired of flashing roms and I hate to wipe every time I flashed so I prefer stock to stop doing that

Yeah, The rom is based off of stock H2 and is supposed to have some battery tweaks to make it last longer. All of the people said battery was good using this combo and 1 person said it's been 1 day 16 minutes, and they had 26% left but they didn't post the usage.

Ok this is with the stock rom. Heavy usage by my means any way. It was on the charger for a few mins here and there. But really not enough to show real battery increase.

The best way to determine battery life (not I played a game for a little, surfed the web over 4G, called some, texted all day) is to take a screenshot of your Screen On time, and overall time since charging. Otherwise, your statements are pointless.

If u have a rooted device u should try the highonandriod Rom it dies have better battery life than stock

Well the purpose of this thread wasn't to solve an issue with my battery life or determine my exact amount battery life, but rather to find out if there are any tricks to improve battery life. So there's no reason for me to post any screens of my battery stats because it's irrelevant to the thread, I was just wondering if anyone knew any tricks or tips they use to improve their battery life.

I'm very happy with Wanam Lite for now, it's so far the smoothest stock rom I've flashed and I'm eagerly awaiting the next update, so I don't really plan on flashing anything else for now. Thanks for the suggestion though, I'll definitely give it a shot when I'm looking for another rom to flash.

Disable auto synchronize. Thats the key.

Don't use the phone. The screen will almost always be your biggest power draw. Screen-on time is relevant because if you have the screen on for three or four hours you aren't going to see battery life that is any better.

Your right, it is relevant when comparing, but I'm not comparing anything here just looking for tips and tricks. I looked at battery stats when I compared the stock battery to the rom battery and recorded both stats on heavy use. If you want statistics, I got 9h 38m of battery use, internet and netflix took up 31% battery consumption, games took up 23%, phone calls and texting took up 12%, and the other 34% is basically screen off time. These were the stats from when I tested it on the Wanam Lite rom. I'm not confused as to why it only lasts about 9 and a half, hours as you can see I was constantly on the phone when I was testing it.

Well not only were you watching a video (I assume, instead of just browsing) Netflix, you were streaming. That probably did a number on your battery. I know I cannot stream Netflix for very long if I want my phone to last through the day. Also games, things that will ramp up the processor, etc while using the screen will tax your battery more than usual.

Some may not like my answer because it removes some bells and whistles, but I suggest turning off all the motion features. Just my two cents. Battery life was better and I found most of the motion features unnecessary.

Yeah, this isn't my everyday use, nor would I do this if I was trying to maximize my battery life. This was purely for testing the battery life on heavy usage and I found that it was only a little bit better when compared to stock. I'm in no way complaining, I think Wanam has done a amazing job with the rom. The stability is great, speed is comparable to JB roms, and battery is a lot better. Unless used heavily as shown above, then it's only slightly better then stock which is kind of odd but makes sense. I was just wondering what all a person could do to maximize their battery life, that's all.

No worries! If you have trouble with idle battery drain, something like Juice Defender will help a lot if you're going to have the phone idle for extended periods of time. Other than that, all I can think of is underclocking (I run at 1350), and sometimes overclocking your min-CPU speed can help as well. The thought behind this is is that the CPU will be able to finish tasks faster, even if slightly, and then be able to go back into deep sleep. I know a lot of people on the Galaxy Nexus forums run 700min, 1000max because of this.

Thanks, I actually didn't know that, I also heard undervolting can increase battery life and reduce the battery/phone heating up but someone said that it can it will have a major effect on the CPU, not sure if it's true or not.

[Q] S3 Battery drain during use

I know there are hundreds of these threads but i was unable to find the information that I'm looking for. But my guess is there is no real answer to my question. But i've been wrong before. Please bear with me
Here goes.
I want to know how to maximize the battery when USING the phone. I dont care about wakelocks or sleep time etc.
I am interested in getting to max out the usage time.
For example when I stream radio and surf the net and text. My phone lasts 2 hours with max birghtness. That seems really short.
- I've done all that I know to minimize power consumption with turning off sync, settings, etc.
- I have tasker starting and stopping data during screen on/off.
- I have the phone UV and under clocked.
- I Limit my phone to 3G only, with no LTE
- Also signal is not a problem since I can stream and surf without an issue. With areas with poor reception. I don’t even use the phone really
-*I also have all the chats turned on include facebook, whats app, etc. Once again, phone is awake. and I'm concerned with its ON screen usage battery time.
- I even have the second CPU setting on conservative. (when set on ondemand it drains even faster)
But during usage, its terribly short! What can I do to prolong the life?
The battery was always like this and I dont believe its defective. With regular use, checking phone (once or twice every hour) can easily last a day. But during multitasking usage I notice the drain to be 49-59% per hour according to battery spy.
I know I can uninstall battery spy/BBS to conserve battery. But I'm looking for what some are reporting (4-5 hours of on screen usage time).
Looking for some guru-like advice Thansk in advanced

Personally, I get the best battery life out of the stock kernel of whatever particular ROM I'm running. I stick with tw based ROMs, and I greenify almost everything! I consistently get between 5 and 6 hours of "screen on" time with the stock battery.

You never said what ROM and kernel combo you're using. I know that I get 3 to 4 hours of screen time depending on the apps used and the connections utilized (wifi, signal strength, LTE or H+, etc). 2 hours definitely sounds low though. I'm using stock debloated ROM right now and stock kernel. I have not modified voltage or clocking in any way (yet).

I didnt really notice any improvements on the KT747 vs stock kernel.
I greenify everything except for the messaging apps. But then again, when my screen is on, i want ot be using those apps.

You're doing heavy multitasking!! It's going to eat the battery, sorry, but no one's going to post a magic "cure" to increase battery life! Buy an extended battery... Problem solved.

Websurf and radio or text and radio is just 2 tasks occuring.
Well I can say that running on Wifi, I can get regular battery life about 4-5 hours of use and over 20 hours of idle time.
The radio seems to be the main culprit, so the question is..... what can be done about that?
I'm asking because
- I flashed diff modems and seems to yield same results
- other S3 from my friends seems to last longer with multitasking
- signal....strong or weak seems to produce same drain.

Battery?

I've had the same problem. I couldn't get the same battery life as others I know. I always turn my GPS off if I didn't need to use it. Google now seemed to kill my battery so I stopped using it. But, the one thing I did notice is that the battery stats can be a little deceiving. If I left my phone off the charger and didn't use it for 10 hours and then started to play a game, it would look like I was getting good battery life as I would have about 60% battery left. Now if I played the game right after unplugging my phone, and then after the same 10 hours I'd be around 40%. Hopefully that makes sense.
One thing that I did do to overcome this was get an extended battery. It does add a little bulk, but now I can use my phone like I want and not have to worry about my phone dying on me at night. I can even forget to plug it in and still have battery the next day. For me I got the hyperion 4200 battery. The Zero Lemon seemed just to big for my tastes.
The other thing is also the ROM. At times I have found the same ROM but a different version exhibited different results. All ROM's offer something different so it is a give and take situation.
I hope this helped.

Yea my gps only turns on when my map turns on via tasker. I also dont have google now on.
Ya i understand what you mean on the percentages.
Ive seen people wiht great battery life, i wanted to try to acheive that without an extended bat. I was wondering if there was somehting that was obvious, or some radio battery drain fix. (I even tried only 3G, and still drains)
Thanks

It's a little hard to compare, but right now I'm on a 4.3 ROM and the battery life has been exceptional. Otherwise the next one that has been closest for me in terms of battery life has been Dandroid. Also, it's hard to judge a ROM after a day.
I guess I should have asked if you have tried or have any interest in a custom ROM.

I've had a hard time getting really good battery life from the stock ROM. At best using greenify, I could prolong it a bit. If you are interested in a stock ROM with some tweaks, I always suggest S3Rx, or Dandroid if you want a slimmed down version without the bloat.
You can always try the power save mode as that does seem to help some, but you may experience some lag.

Ive frozen most of the bloat, greenified everything, plus I unclocked and under volted it, so any lag I would feel from power safe wont affect me since i believe power save throttles to 1350 ish .

[Q] Cyanogenmod or Android Revolution 6 in terms of battery life

What would be the best ROM for battery life? I'm using CyanogenMod atm and the battery life is decent. If I flash Android Rev. would I sacrifice battery life and if so by how much?

As mentioned, battery life is completely up to your usage. Some steps to try though which can be used across any rom is to give Rom Cleaner a shot and to use Greenify. This will rid any rom of bloat that could be sucking up battery and better allow the device to enter deep sleep where the real battery savings are had.
A well optimized kernel would give you some savings as well. I can personally say that on ARHD 5.5 with Elemental kernel .15 I'm seeing about 70% battery left at the end of a normal day. For me though that may only be one 20 minute call and an hour of screen on time. Even when flashing and messing with tons of settings for hours, the phone has never reached a critical battery level for me. I

It's more about the way you optimize (or debloat) your phone , than the ROM you are running. Use battery monitors like GSam or Battery Drain Analyzer and freeze apps that are causing you huge drain. Greenify is also good. Ideally on the M8 you can expect around 6 hours of screen time if you're optimized correctly.

This. I am able to get about 6 hours on stock, ARHD and Insertcoin. With power saver on, that ends up around 7-8 hours of screen time. Coming from a Nexus 5 that got 4 hours typically, I'm pretty satisfied. I'm inclined to believe ARHD will get "slightly" better battery life than CM since it is based off the stock ROM on the M8.

Generally the OEM skinned roms have better battery life and benchmark scores opposed to aosp. Happens all the time on Sammy phones and HTC apparently too. Posts above mine cover most you'll need to know. Its all about optimization and frankly that part is extremely fun and especially rewarding IMO. Gives me an idea for something like a community made thread on different battery tweaks/voltages :good:

Thanks for all the feedback guys
I'm currently using Android Rev. 6.1 odexed (using ART atm) with ElementalX 0.10. I don't know if this is a placebo effect or not, but after flashing ElementalX(with default settings) my battery life seems worse :/

ROM with the best battery?

Which ROM has the best battery? Is it Stock because it has more battery optimizations or is it a custom ROM as they are more simple?
Please comment your setup along with your ROM and usage.
Thanks for the help

i am using resurrection 5.8.3 and the battery life is great!
at the moment i am 10h SOT with 40% battery remaining

I think stock is a safe bet. Coming from an LG G2, the P2 surpasses my wildest dreams. Could possibly get 20 hours SOT with very light use.

I agree.
I believe Lenovo optimized everything about the official ROM so as to provide huge battery life, from the auto brightness all the way to background process killing and signal search. I doubt any other ROM can achieve the same result without being severely hampered, unless it's some battery driven ROM.
Rooting the device while keeping the default ROM might allow you to tweak things a bit further and squeeze some more juice out of it, although I doubt much more can be done.
Then again, you might want to consider what you use the P2 for, and how much battery life can be expected from that usage... For example, I use mine for gaming all day on mobile data, and it lasts 8 to 10 hours! My previous device lasted 2 hours and a half under the same conditions with any ROM I tried, so I really don't expect better.

8.1 Battery Drainig - Recommended EX Kernel Settings?

I'm new to my Pixel 2 XL and have the 8.1 update and am seeing horrible battery life. Noticed others in here also experiencing this and wondered if any of you have some recommended settings for EX Kernel that can improve battery life? I only use the phone for notes, camera, calls, messages, etc... Daily use type of stuff. I don't play any games on my phone other than Hearthstone and it doesn't require much to be smooth and I watch some YouTube here and there but it also doesn't require much so anything I can do to get those 6 hour SoTs everyone raves about with this phone.
Standby is great, in use is just embarrassing.

Mine is opposite. It easy to get 6 or more hours SOT using the phone but the thing drops like 10% battery overnight even with battery and data saver on.

A kernel will not stop a badly behaving app from drawing too much power, or not dozing when it is supposed to. You would be better served in using a battery drain app to find your wakelock/bad actors and deal with them. Beyond the information you can get from the improved Google battery applet, GSam and BBS are two apps that can help pinpoint the application or service causing excessive battery drain. It is not the kernel, and as flar2 states, the new chips are so efficient with power there is almost no room for improvement battery-wise. Most people leave it on the default settings, and use it for extra features and customization.
https://elementalx.org/the-truth-about-kernels-and-battery-life/

I agree 100%, I just thought some settings adjustments with the kernel could do some good and maybe someone might have some ideas on what would help the in-use battery consumption. I'm currently clean flashed with only Google APPs and Nova Launcher installed along with EX Kernel and Magisk no modules. Battery drain only shows android system... Not a lot to tell me what it really is. Will try the apps you suggest
