Tips for Best Battery - AT&T, Rogers HTC One X, Telstra One XL

So guys, its a fact we have a small battery for our phone but I was wondering, how do you get the best battery life?
Just post anything! What ROM your using, what kernel, your kernel settings or maybe a tweak you found.
I want this to become a help center for people who suffer from bad battery
EDIT: Also, have you guys expierenced a difference with unfervolting?

Try Greenify in the Play Store. It seems to help for me.

I use a Tasker profile that will disable mobile data when my screen is off and when it's not being used. Don't know if it helps or not I don't worry about battery because I have a a portable battery pack charger thing

Pretty sure there is already one of these.
Elementalx kernel, greenify to hibernate Google maps, use WiFi as much as possible.

I wholeheartedly believe in Greenify! I have it on my tablet and phone. I've seen a jump in battery life by about 30% since installing it. Not sure if you will have the same type of luck or not.

There's many factors that can be affecting your battery. More importantly it depends on the type of rom you are using, assuming it's sense based... Try using elementalx 6.6 kernel, it'll help your battery; tweaked with the right settings. Power saver also seems to help a bit.

This probably isn't what you had in mind but my best tip is to keep my old iPhone with me and use it for media consumption. That way my android always has a full battery for actual getting work done.

I've noticed on CleanRom that maps uses a lot of battery %. I've never looked into it, but I'm guessing you've found the same problem.

Why not just Greenify maps as suggested by others. Did wonders for my battery life, used to go to 15% in the evening, now regularly above 60%. I also use autostarts to kill some other processes that are launched by default

I'm using the stock Android 4.1.1 ROM unrooted. With my normal usage, I can get through two full days. I make sure to toggle off WiFi and mobile data when not in use, as well as toggle on the "battery saver" built into Sense. I also turn off sync for everything (Facebook, Twitter, etc) except for two Gmail accounts which only check for email. It's about on par with my old Nexus One that I moved from. Keep in mind, however, that I just got the phone and these might change, but this is what I've noticed thus far.

A combination of 2xBattery (toggles data connections when screen off) Tasker (toggle data in different times/locations) and Greenify.

When it comes to battery life, the basics really are the most important.
here's a couple:
1. Don't use auto brightness. It tends to keep the display super bright even when it's not needed. The display may very well be the component that draws the most power in the entire phone! Look for widgets that let you select manually (I use "Brightness widget - backlight" from Google Play and even manually, I set the brightest it can go to 79%) or apps that still let you have auto brightness but more controlled (Try "Yet another auto brightness" from Play Store).
2. Use a setup as stock as possible. I know some people are going to disagree with me , but having your phone as close to stock as possible will have the best proven battery life. I think some of the developers here do amazing work on custom roms and kernels, but when people report good battery life you should keep in mind that are so many factors involved that it's hard to replicate it if you want to. Carriers test their phones extensively to ensure good battery life, and while I am NOT saying custom roms and kernels is a bad idea, I AM saying that I believe a stock experience is a more proven option.
3. It also has been proven that undervolting does NOT help with battery life because not only the difference in millivolts is negligible, it may cause instability and finally a reboot, which just happens to be the biggest software-related power drainer.
Hope this helps

im running clearrom 6.5 but i havnt been able to get greenify to work really. when i install it, it only shows a couple apps that i dont really use to begin with. correct me if i am mistaken, but greenify will hibernate/shut off running apps and the apps that the greenify app shows are apps that are currently running?

Correct. If the app you want to hibernate isnt running you would have to run it to add it to the hibernate list.

I don't know if I agree 100% on that one. Undervolting can reduce the amount of heat discharge caused by too much voltage being provided. A hot battery affects battery life both in the short term, and the long term.
Yes, not all phones can handle undervolting (because they're already receiving a good amount of voltage out of the box), and will glitch and reboot, which drains battery.
But, for phones like mine (which I can generally UV by about -75mv without adverse effects), the reduction in heat can only be a good thing for my battery life.
Sent from my Evita using XDA Premium

Heat itself should not cause your battery to drain quicker. Heat is moreso an effect from the cause of something causing the battery to drain rather than heat causing the battery to drain faster. Heat can damage the battery which would cause it to drain faster... so what I mean to say is heat will often accompany the battery draining quickly but not be the cause of it. Hopefully this post makes sense.
Sent from my HTC One X using xda app-developers app

Yeah it's the damage caused by heat that I was talking about. I've heard a hot battery will discharge quicker though. But heat is also a side-effect of the battery providing the CPU with too much voltage, that extra voltage being provided has nowhere to go so that energy ends being dispersed in the form of heat. Which in turn damages the battery.

That is mostly incorrect. The voltage options we can tweak are not enough to make such a big difference, so you can and will still experience heat even with an undervolted cpu, provided the load is the same. And that's my point, that the difference in undervolting in millivolts is negligible yet one reboot can wipe out an entire day's worth of battery life "savings" from an undervolted CPU.

Ok well all I can say is UV'ing definitely decreases heat for me, particularly when playing games (which is when it heats up the most), and I can safely operate without reboots. Before you say it's a placebo effect, I check my temp regularly to verify it.

does anyone else use setcpu on the g2x

in the pursuit of an everlasting battery, i installed setcpu on my phone yesterday-- i set it to a max of 400 when the screen is off, 800 when overheating, 700 when at 75% of battery, 500 when at 50%, normal when ac charing and 70% when usb charging (so i can hopefully charge faster in the car).
i havent been an android user for awhile and dont know if setcpu is one of those programs that use more battery than it saves i.e. "bloated". also, i know it sort of defeats the purpose of the dual core to underclock, but i'm going to be honest, i'm an iming, texting, browsing, sync two emails, words with friends, shopkick kind of gal...
ewww Words with Friends. WordFeud FTW!
I have never messed with SetCPU aside on my Android tablet because it had a problem sleeping. I can say that it did wonders for my tablet, I can't see why it wouldn't be the same in this case.
I don't know if I would set it to vary the speeds based on the battery readings. My tablet I had the CPU set to like "72mhz" when the screen was off and On Demand when the screen was on.
I also used Advanced Task Killer to kill all tasks when the screen was shut off because my son was launching games and leaving them run in the background. Between the two, the unit was like a whole other unit. That might be overkill but if you are worried about saving battery, might as well kill all those background apps too. Wouldn't hurt to test it. My biggest concern would be your Email Sync and IMing.
So in Advanced Task Killer, just have it ignore said apps and kill everything else.
yes i have am using it on my G2X i only have a screen off profile which is set at 216-312. I dont really want to lose speed just because my battery is low and while charging the phone doesn't heat up like my N1 did so i don't see a need for a profile there. It does work and it does work well.

hey! theres nothing wrong with wwf.. :]
i froze many bloat apps with titanium, and games too since i'm not much of a gamer :/ yeah, iw as thinking of taking off the syncing and iming, but i get very aggressive and could see myself dumbing down my smartphone for the sake of the battery.
with setcpu the way i described, i have noticed a loss of 5.5% an hour with normal use during the workday-- which is when i need to save my battery since i cant charge at work... i think i can live with 6% an hour... maybe.
but i did like underclocking for certain temperatures, because for some reason the phone is feeling hot in my pocket and has temps of about 91
Advanced task killer? Why am I hearing it's bad for your phone? Even when I installed it, I was losing a lot, even with Juice defender I'm losing a lot. I hardly have any apps, and I'm afraid to use my phone because of my battery.
Anyone know what I can do?
Once undervolted kernels start rolling out, battery life should improve marginally.

Best battery Saver

Idk if this goes in Q/A or not I never had a Q/A section as I came from the amaze but anyway. What battery savers do you guys find best? I Use Batter Defender but doesn't seem to really extend it. Would i be better of not using one at all?
I use 3 programs to help me maximize my battery life.
1) Badass Battery Monitor to figure out what's sucking juice, how long I've left, and how long until I'm full.
2) 2x Battery to manage background data. This probably saves me the most battery by disabling that data transfer a lot of the time.
3) Lux Auto Brightness to tweak my screen brightness. It's pretty much on "dark" now all the time aside for when I'm in really bright light.
JuiceDefender
I use the free version and it's very good!
I think the most effective battery saver is to flash a kernel that has become voltage control features and undervolt the cpu.

I'm not a fan of under volting the CPU. Mainly because if my understanding of Ohms Law is correct, it's pointless. And my personal experience with it seems to corroborate my feelings.
Under volting the CPU in my experience just introduces stability and reliability issues. I've personally never seen any battery savings from it, especially since the CPU should, theoretically, just draw more current (I) to compensate for the lower voltage (E). It's watts (P = ExI) that matter, and the CPU, if I understand correctly, is going to demand the necessary P for the frequency requested. So under volting either starves the CPU (it can't get enough P), or over currents it (it draws more I to compensate for less E). There are slight variations in each CPU, obviously, which may allow for a margin of under volting to be possible without issue, but the battery savings of this, I feel, are so small, any you notice are most likely a placebo effect. Your screen, and apps constantly polling the CPU or network are your biggest source of battery drain to worry about IMHO.

I use Power Controls widget.
Unless I'm actively using internet, I make sure to turn 4G data to 2G. That alone saves so much battery. If I want further battery saved, I disable internet completely with a touch of a widget. Now my phone will last a week just by what phones do best: Making phonecalls and texting.

With an higher frequency the phone will use more power, like a pc processor when you overclock it so this is natural, but overclocking/downclocking has nothing to do with undervolting, MadJoe is right.
With JuiceDefender for example you can set your 3g/4g to shut off when you don't use the phone, it activates 3g/4g when you use your phone and at regular intervals in backgroud so it can fetch emails etc.
All automatic so you don't have to switch off and back on network connection every time.
As network connection is one of the services that consumes the battery a lot this is really effective and really improves battery life!
I've read a lot of complaints about these PowerManagement Apps using more battery life then they safe.
I don't know if this is right.
At the moment I'm running CM9 with modified auto-brightness options, auto-sync and 2G/3G/WIFI always on.
I'm really happy with the battery life I get, so I don't see why you would need a Battery Saver app with this phone.

CM 10 performance settings

I just got upgraded from CM 9 stable to CM 10 stable and I love it. Only problem is battery life. I feel about a 10-15% reduction with the new upgrade. I've had CM 10 for about 4 days now. I don't want to touch the performance settings without knowing what I'm doing. Is there a way to change my performance settings to extend the battery life? Also has anybody played with a different kernel with CM 10 stable? Thanks

Don't worry about changing the cpu and governor settings. There is an option to set at boot. Make sure that is disabled, so if you have any problems a reboot will go back to default settings. I use the conservative governor, and have my minimum cpu speed set to 192. I've read that that speed is not entirely stable for many people, but seems to be working fine for me. That has been pretty good for battery life for me. I believe the default governor is interactive now, and the minimum cpu speed is set to 384 by default.
Do you just "feel" a battery difference, or do you have any actual numbers to back up that assertion? Keep a close eye on Settings / Battery and use Better Battery Stats to record solid numbers and identify what's actually eating your battery.
Also turn off google now location settings if ur not using it. They are really hard on the battery.

Thanks for the replies.
It seems to be my screen that is responsible for eating up my battery. Have had the phone disconnected from the charger for 4 hours now and all I've done is 20 min with screen time doing a little bit of texting and facebook and my charge is at 75. I have the automatic brightness setting off and put my setting at pretty low.
The cell stand-by battery usage is 8% during these 4 hours. Should I maybe try another radio or is this normal? It lost signal for about 10 min today.
Just turned off google now and selected the conservative governor. Let's see if this makes a difference.
I used to be able to go all day with my phone with CM 9 and I even have the nexus battery.
Thank you for all your help
That's most definitely not normal, at least in my experience. Are you using the vanilla CM10 or some variant?
Some things to try:
Install Better Battery Stats (find the free version on XDA via a search) to see if any apps are causing wakelocks. This is a must.
Use CPU Spy or something similar to see if your phone is entering Deep Sleep. This is a must.
Turn off Google Now unless you actually use it
Turn off all unnecessary radios (WiFi, Bluetooth, GPS) unless you're actually using them
Turn off all auto-refresh settings in every app you have -- all social apps and weather are the biggies
For me, turning off the default auto-refresh in Facebook, Google+ and Twitter are massive savings alone, then Settings / Battery & BBS will help you locate the remainder of the headaches quite easily.
You might want to consider swapping kernels too, or at the very least reconsider your CPU governor and scheduler settings.
I would stay away from conservative governor you won't get much performance out of that, stick with what comes stock and use on demand.... even the default interactive sucks my battery down

I have noticed that my phone lost signal 4 times during the day for periods varying 5-10 min. I am currently on the I727UCLF6 radio. I'm thinking maybe I should try another one. Could that help with that battery maybe?
I have been thinking about switching kernels but I am a little doubtful because I don't want to mess up my phone too much since I so heavily depend on it. I loved the hotcakez kernel that came with AOCP, maybe i'll give it a shot this weekend.
Thanks for all the help people! Def the best forum by far on the web.

Just do a nandroid backup of the entire phone first before installing a new kernel and your risk drops to zero. If you install it and it all goes to hell, just boot back into recovery and restore your backup.
As for radio ... if you drop signal that often and your phone is constantly searching for one, I suppose that could impact the battery, sure. Are you certain you're in an area with solid coverage, though?
Learn more about the different governors and schedulers: http://forum.xda-developers.com/showthread.php?t=1950084
Yea I might have to play around with some kernels this weekend. Luckily it is a long weekend so I'll have some time if I mess up
My phone will go from 4 bars and a good signal at -78 dBM in my apartment and then randomly I'll lose signal for abut 5-10 minutes. A restart usually does the trick or I can just wait until it regains the signal which can be frustrating. I never had any problems with my signal at home running CM 10 so that leads me to think that there might be some problems with the radio.
Just want to confirm that these are the 5 radios I can use for AT&T even though I'm running JB.
http://forum.xda-developers.com/showthread.php?t=1754473
I've been using a UCLI3 modem I found on XDA a couple of weeks ago, it has been incredibly stable and strong for me. But as many people far wiser than me have said elsewhere, everyone's mileage with radios varies and it really just takes some testing to see what works best for you.
so I should be able to run the 5 ICS radios I found eventho im running jb right?

App is from Qualcomm.
I've never used apps the limit functionality to save battery before, but if anyone would know how to do this right, it should be Qualcomm.
Snapdragon™ BatteryGuru extends battery performance and improves overall user experience by intelligently making changes that optimize Snapdragon device functionality. This app:
• Delivers longer battery life with fewer charges
• Intelligently learns how you use your Snapdragon smartphone and optimizes your device without disabling smartphone functionality
• Requires no user configuration - Snapdragon BatteryGuru automatically learns and adjusts the smartphone settings so you don’t have to.
After a brief 2-4 day introduction period, Snapdragon BatteryGuru learns the user’s behaviors and then notifies the user that it is ready to extend the battery life and improve the experience. Snapdragon BatteryGuru continues to operate in the background, deepening its understanding of the user and further optimizing the experience over time.
Thanks man!
Will give it a go.
I'm not really sure on what the value of these apps are.
Letting my phone do whatever it wants when I'm on wifi and my phone is sitting idle, my phone uses around 1%/hour of battery life.
Some portion of that is all this app could really save then, right?
Why bother if, in exchange, I'm possibly having delayed notifications, apps not updating in the background, etc.?
Sounds like a bunch of BS to me.
I'll be shocked if this makes any discernable difference.

It seems to keep me from adjusting my CPU with rom toolbox pro or system tuner pro. Can someone else that is running a custom kernal (IMO 2.0) and let me know if they can adjust theirs.
Sent from my Nexus 7 using Tapatalk HD
This is an app written and distributed by a component manufacturer. They will cut speed/processing power as much as they can to make the device use less battery. This inherently means the app will take control of the CPU/governor adjustments. A kernel such as KT with an app that LOCKS frequencies may prevent this, but also will render the app useless.
They aren't concerned with the same things as we in the rooting world are. We want to push as much processing power as possible while using the least amount of electrical power needed, not slow the device down while hoping ppl don't notice. Lol..
I too experienced battery drain from this app.

That's a 'feature' of the ICS+ kernels. While 100MHZ is the minimum, if it's actually set to that, the kernel is set to go back to 200MHZ anytime it gets the chance. You can watch this happen if your scheduler/governor app actually updates on current min/max speeds. ROM Toolbox PRO, SetCPU, ROM Control, and CM's Performance controls all display this shifting, though with luck you can sometimes get it to stick at 100MHZ. It just takes some persistence.
The modem on the phone isn't very good.
It even happens on stock where if you go in and out of dead zones, it will "SEARCH" for network and become burning hot, so it's a common problem that happens year round. It's a great way to kill battery. That's also why if you leave you phone in a sock drawer, it's going to last longer than if it's in your pocket walking around.

It even happens on stock where if you go in and out of dead zones, it will "SEARCH" for network and become burning hot, so it's a common problem that happens year round. It's a great way to kill battery. That's also why if you leave you phone in a sock drawer, it's going to last longer than if it's in your pocket walking around.

I never got my phone to go into deep sleep when I selected ondemand (or maybe it was ondemandx). I would try a couple of the other governors & see if that would help.

OndemandX gives me good sleep, but forces the phone to minimum speeds when the screen is off. That tends to cause issues if I'm trying to use GPS or music without the screen burning.
As to what will work best... that depends on unique your phone, its apps, any tweaks that have been made, and your specific combination of scheduler/governor settings. I'm a fan of SIO, but sometimes the tweaks make that (and deadline) stick at max MHZ, in which case noop is great. At various times, I go with any of the SA2-based 'intelligent' options (SavagedZen, brazilianwax, SmoothAss, or SmartAssv2) or the OndemandX/Conservative basic sets. The others have gotten stuck more often and tended to allocate more processor than I think it needs.
I've always had the best luck with smartassv2. I think it's a good tradeoff between good battery life and quick processor speedups in order to prevent lag, plus I haven't had the issue of the processor locking up while the screen is off.

That's usually the one I always fall back on too despite new ones all the time and everything, it's my default now on any ROM.
