Another battery life question...

I have a buddy with a droid x that gets RIDICULOUS battery life. What is it that causes such a difference in endurance? I mean most of the other specs basically match up... Is it htc related? Can I get "droid-like" battery life somehow? I'm on fresh 3.3 with netarchy 4.1.9.1 bfs

I havent played much with the DroidX but from what I have read it has a power profile managment on it much like a laptop . I believe that is the part Motorola put in the phone . Profiles like LONGER BATTERY LIFE , or MORE PERFORMANCE . Something Im kinda surprised the EVO wasnt given but I make it thorugh the day on one charge

Are you rooted?

Please keep in mind the apps you downloaded and the widgets you have set-up on your screens. Some apps require to be run in the background eventhough they are NOT used by you at the time, such as Google Talk, Qik, Fring, pedometer, and anything that needs to be "ON"...thats one of the culprit on battery drain you might want to look into.
Having one widget per homescreen is ideal, in my opinion..and learned that by having multiple widgets in one screen, is another culprit in battery drain due to it requiring to work upfront, for example, Facebook widget needs to be on constantly and updated for as long as that widget is there, regardless if you touched/used it or not.
Now, for the MOST OBVIOUS part...turning off GPS, WiFi, 4G, and bs when you DON'T need them, by following hot sexy COMMON SENSE, you should get AT LEAST 3 hours more on your battery. Pure sexy common sense LOL ;-)

Greetings,
I couldn't agree more with all the things you noted in your reply.
I rooted mine, and deleted many apps I don't use, but insisted on starting up
even if I had already killed them in the manage applications section.
But I was amazed at how short the life was in spite of having done that. I quickly
discovered (as you noted) that keeping 4G on, drains the batt.
In fact, for me anyway, it really drains the batt!
Just thought I'd mention it, because it was really surprising to me just how bad
an affect on the battery 4G was - bummer.
--Chris

Mine usually gets between 36-55 hours on a charge (record is 58 so far) with about 3-5 hours of "use" on the stock battery. I don't use it to play games or watch movies, just phone, internet, email, etc - widgets all over the place. Gmail push is always on as well. In fact, I unplugged it last at 10:50pm on the 28th (34 hours ago) and I'm at 48% still.
The biggest thing I've found is download setCPU and adjust the CPU frequency to 245 MHz when the screen is off. That saves a lot. Other then that I keep it at 998 MHz (max speed) all other times. I am playing around with tasker and turning airplane mode on while I sleep, but that seems to have a minimal effect, saving around 2% over 8 hours. I use tasker to turn GPS off unless I'm using one of my GPS-enabled programs, although that doesn't seem to do much either.
I'm running just a basic sense rom with a stock kernel, nothing special. rooted with clockworkmod and that's all I've done rom/kernel-wise.
If you actually use your phone a lot I'm not sure there's much you can do besides get a bigger battery. If you just use it mostly as a phone and less as a PMP or gaming device you should be able to get some nice results.
EDIT: Oh yea, and don't use a task killer (I don't). From what I've read those can actually cause the phone to consume MORE power as services are being killed and opened constantly. Android is very good about leaving tasks open in the background without them consuming power. Opening and closing them constantly is another story.

I wish I could figure this out too. I've been switching between a ton of kernels and roms and can't seem to find anything with good battery life. My phones been unplugged for about 2 1/2 hours and I'm at 53% battery life. No widgets running and just average usage.
Running virusrom and kings #9 and a lot of other roms and battery life is a joke.

So far, the best battery combo I've found is fresh 3.2 with it's stock rom and I returned to it last night. Some say 3.3 is as good or better but I can't seem to get those same results...
But my real question is, why is the droid able to get such great life?

What I have found to help most of all is to NOT use the Mail app - it drains the battery like crazy, especially if you are popping several accounts. Instead, use the gmail client and set it up to pop your other accounts, and push them to you. This literally trippled my battery life. And it is way faster than the 15 minute intervals that the mail app gives you. Give it a shot, you will be pleasantly surprised.

Best rom for battery? Current rom burns 1% per minute.

Currently using latest calk rom I get about 2 hours using my phone for browsing thr internet at home. When 3g is turned on it drains even faster.
It has always been like this. If the phone is set on idle without 3g and wifi it lasts about 10 hours.
also it takes about 3 to 4 hours to fully charge, i feel this is too long.
so any rom that might help me? is the battery faulty?

Blazer ROM

why are you using your phone to browse all day long ? use a pc or a tablet. its a phone not a desktop pc. plus put it into airplane mode and then turn wifi on, it disables the cel/data radios hence the battery last longer. If your phone takes 3-4 hours to charge from 0-100 something is wrong with it. turn if off and charge it, cuts down charging time A LOT !

That is ridiculous. But I've been using Blazer Rom for about 2 weeks now and I always get 30 hours+ battery life. I just got 3.8 and I hit over 40 hours just this weekend.

well, um, wow, those are some ... great suggestions...
you might have a bad batt, sure.
i would think it is likely something else though.
a few things off the top of my head.
is this on a "clean install"?
is there some app you have loaded that might be pinging/updating constantly? (I'm on the exact same rom, getting all day at least)
what modem are you on?
did you flash a custom kernel?
do you know how to take a screenshot of battery usage? show us what processes are eating it?

Nice miracle rom, bet I could kill your phone in 6 hours using it . I get 20-30 hours on my days off. But no rom will make up for the amount of use one can put into their phone.

I get great battery life with Blazer 3.8.
Idk about 40 hours (WOW!) but I do get around 3-4%/hour battery drain so it's not bad at all.

Try re flashing the ROM. That sounds abnormally for ANY rom.

It could be a bad ROM (bad install, not the ROM itself), but don't presume that's the case.
Measuring whether the phone is draining appropriately is difficult to do when it's in active use (e.g., 2 hours of browsing) ; thus most people measure effective drain by measuring the drain rate when the phone is 'sleeping' -- though in some cases a bad app or bad install will prevent the phone from sleeping.
I would recommend charging the phone to full, leave all default radios on (GPS/Wifi/3g), and let it sit for an hour or two. If you're losing more than ~3-5%/hour, then you have a problem.
Tools you can use:
- CPU Spy - Will show you whether your phone is entering Sleep state or not
- Battery Monitor Widget Pro - will measure your mA drain rate; during sleep, you'd want it to be at least below 20mA, ideally below 10mA (note, this app requires a couple of charge/discharge cycles before its measurements are reliable).
- Better Battery Stats -- If you find your device is NOT sleeping, this will help you figure out what applications (including the kernel) may be preventing the device from sleeping.

Your point? I could kill my phone in 6 hours too, but why would I want to do that? I play games all the time when I'm out at work or just out in general and I still get over 24 hours of battery. I never use my phone when I'm at home, that's what I have my tv and computer for.

how long has it been since you flashed? Maybe it needs a few cycles to settle. Do you have any wake lock issues? get betterbatterystats app, free for xda members, to check for kernel or partial wake locks.
I'm on BlazerROM 3.7 and getting about 1% every 2 hours on idle. It took me a week to see the battery life i'm getting now. My wife is on calks 2.8.1, I don't know what shes getting but when she gets home from work, she's still around 50%. On stock, she was typically around 30% already.

how do you get betterbatterystats for free as an xda member?

I'm on blazers and i'm at 79% battery at the 7hr mark on battery.

I have seen this "mystery battery drain" problem in other threads. There is usually an app responsible. Try Watchdog, its not bad.
I also have heard that SD card or file errors can be responsible for the drain. Formatting the memory takes care of the problem. If it were me, I would format the memory, then run chkdsk (Windoze, or the equivalent in another OS) to mark bad sectors. In the case of internal memory, you will have to do that through the USB cable. Do so at your own risk, of course

The point is you walk into someones situation and act as if their usage of the device on whatever rom your on is going to produce a parallel experience. One of the biggest factors no matter the rom is screen brightness. If you spend most of your time out doors the experience is completely different even with the same usage patterns otherwise. I love screen brightness personally, haptic feedback is nice too who cares about the battery when the experience is better?
I have games on the phone, GTA III, MC2/3, Dead Space, etc. I don't actually play them. I remote into my PC, browser the web. I have a TON of apps that use the phone idle/background. I keep steam and im+ pro going. I let TEP ping GPS data every 10 minutes. Weather widget, google voice, etc. I even have Samsung Apps installed with its oh so horrible push service that apparently rapes peoples batteries... cant say it hurts at all.
Today was a day for me where my boss was around so I couldn't use the device much and when i did it meant leaving things like a remote client on because I couldn't touch it to turn it off. 52% battery was left after 12 hours so it obviously was going to survive the 16 hours I am awake, going to sleep now so it would easily last 24 hours. But the battery being Li-Ion and me actually caring about it, its going on the charger. Tomorrow could be 30 and the next day will probably be 8 hours.
As far as the topic is progressing. Check your apps and your settings. Ive had battery life so bad the phone died on the charger. Same rom, same apps slightly different setup later and I am getting good to acceptable and that constant wake this guy is probably getting is gone.

If your using a lot of push apps, you're battery becomes nothing more than a decoration, lol. Apps like aim, kik, basically all the chat ones. Games like words with friends. The more apps you have checking for updates on top of heavy usage with kill your battery fairly efficiently

Which personally was part of the issue before on my setup. I still have them going again and battery life is decent. I mean Id want 16 hours out of a phone surely whatever my day is Ill have it on a charger by bed time.
I personally usually get 12 hours or more on days Im not using it constantly, 6 to 8 if I am using it every waking second. 24+ on days off. Haven't tried blazer in particular myself yet but Calks seems manageable even for demanding use.

Guys please help!

Okay, I am having a very frustrating problem that I did not originally have. My phone can last me half the day!! It is very frustrating to have my phone turn off on me everyday at 5 pm ..I love this phone but this is unbearable, especially considering that this is with very, very, very minimal use. If I actually use it the phone intensely, it will drain completely in 1.5 hours. ..It was not this bad a couple of months ago.
I have bullet kernel, and stock GB rom (2.3.5)
I had it always used it on "lag free" setting OC to 1.6 but I changed it to conservative mode to try and see if that would help and it didn't. I even used the core sleeper script from the developer's section and that didn't help either. I had changed radios a number of times when I was tinkering with custom ICS roms. I got my gf this phone a few weeks ago and put the same setup on the phone and she is getting the same battery life. I bought it used.
Does anyone have any suggestions!?? ...I would really appreciate it

You can extend battery life anumber of ways.. Tell me what Is on bt by wifi sync the screen ways ths most energy so turn that down as low a you can... Sounds like you are on an old ROM ...prolly eagles blood?
I suggest digital warfare 2.7 if you are on TMobile. Great battery life. Also flash your radio before your ROM and make sure you are flashing over a clean slate.

I am running on the Stock ROM with android 2.3.5
I am running off a nandroid backup I had restored after having an ICS rom on the phone for a few days. I used darkside superwipe, then flashed radio, then restored the ROM backup.
I always keep GPS, wifi and bluetooth off when I am not using them. I keep wifi on if I know I will be home for the day so I can use that instead of 4G ...I keep my brightness on the lowest setting.
Even with the sleeper core script, turning off 1 core, its still drains out at over 7% per hour without ever even touching the phone. Something is definitely wrong because I read people on the Sleeper Core thread saying they lost 3% in about 6 hours of standby with the script running.
the battery really should be in good condition because the phone is less than 8 months old and I frequently switch between a backup battery (cheap eBay battery), so that should preserve the original a little and even w/o the 2nd battery, the battery shouldn't need replacement this soon.

Have you tried using an app like Badass Battery Monitor to check what's app or process is eating up your battery?
Also, does your spare battery die quickly as well?

No, I haven't used a 3rd party battery monitor app, I just look at the system menu section that tells me what things are using battery and it is says my screen is using 50% ...my spare battery dies very very quickly. But it always has died this quick since the day I bought it because it is a crappy Chinese battery from eBay that I bought for $4 ...the first few times I used it, it would last about half as long as my original samsung battery

You should try to forget about the extra battery... and charge your phone while off then after ten or more mins of it being fully charged unplug then wait and plug back in to charger... It will likely charge again for a minute... Do that little cycle to get a full charge. After i do that i enter CWM and reset batty stats. There is more on this if you google it.

For those with battery issues.

Leave ICS and get back on GB.
Ive had this phone since the day it came out. Switched to ICS once the developers started dropping ICS leaks, etc.
For the past 2 weeks for some reason, Ive had nothing but HORRIBLE and i mean HORRIBLE battery life. Phone would not last me more than 4-5 hours of heavy use. I'd have to carry around my portable battery pack to charge the phone on the go. I did everything to my knowledge to try and conserve battery life. CPU tweaks, battery monitoring, tried different ROMs, Kernels, Modems, etc, etc. Nothing would significantly improve battery life. I even went ahead and ordered a new battery last week to remedy this problem (which has not yet been delivered/used)
2 Days ago I flashed back to Blazer 4.0 ROM (GB).
I unplugged my phone yesterday morning at exactly 7:30am. Did not step back into my house until 530 which at that point I was at 35% and had been using my phone all day as I normally would. Web browsing, tons of texts, Used Navigation for about 2 hours, etc. I did not plug my phone to the charger until 10pm. Phone was on 19% then. Mind you, this is on the first day of the Phone being on a new ROM/GB so the battery has not yet settled/calibrated as Its only been charged Once since flashing over.
I refuse to switch back to ICS for the sole reason that battery levels have obviously improved with something as simple as switching back to GB.
Just a heads up for anyone with ICS on their E4GT having issues with battery life.

If only I got a dollar for all the times a thread like this is made.. I'd be rich. Blah blah ICS sucks yes we know... So far my phone must be a super phone because it's handling ICS well.

I agree with you, Ray. I'd also be rich for every time I've read of E4GT owners who's phones are running ICS with no problems. But then theres the bunch who also complain that they have problems. I never stated ICS sucks. At this point these phones are old by today's standards. Be glad you're one of the ones who's running ICS with no issues. I for one will stay on GB until I switch to a new carrier/new hardware sometime soon.
Just thought I'd give some feedback of my experience with battery issues on ICS in comparison to then switching back to GB.

I don't know if you've tried Blazers ICS ROM, but that thing has some AMAZING battery life. I've been running it for a few weeks now, everyday I get at least 12 hours of moderate to heavy use, without my own tweaks, and by the time I connect to charger I'm at 35%

Arguments apart
i have a few friends all on this or that ICS and none of them is happy with the backup
whatever its a fact ICS goodness never really reached E4GT, lets hope FI03 onwards some sense prevails at those losers at sammy and they push something which we can smile about.
FYI i am also on ICS Rom , still in testing phase after getting my new white beast 10 days back , already tried like 3 , each for three days
running galaxy 1.8 since yday and hoping it shapes well otherwise i ll also move back to GB

I've tried multiple ICS rooms and I've always gotten great battery life (14+ hours with 3+ hours screen on time).
The only times I've ever had battery life issues were when a certain app was the culprit and was keeping my phone from deep sleep or causing frequent wakes, which is almost always the case with poor battery life issues.
Check out an app called GSAM Battery.. it will tell you what is using up your battery in easy to read graphs and percentages. Also, check out CPU Spy to see if your phone is actually going to deep sleep mode when you turn your screen off--again, it shows you in an easy to read chart with times in each state.

Only the stock ICS rom is garbage with poor battery life and stupid stuff like grey text on black back ground. I have ran several custom ROMs and they all provided better battery life. As I have said before, I got 99 problems but battery life ain't one of them. You must be doing it wrong.

Still waiting for the new battery to arrive. I would love to try it but I'm in the midst of a heavy usage of Verizon PRL on my phone. Sprint doesn't like heavy roaming users from what I've been reading. Sprint 3G in my neighborhood here in NYC sucks Donkey nuts. I can cross the street and get 3 bars more than I have sitting on my front porch. But thats a whole other topic of discussion.
Im not sure why my phone couldnt play well with ICS but it really was horrible. I consider myself a heavy user and ICS couldnt keep up with battery demands. I tried undervolting, etc. Oh well. Been eyeing the SGS3 or the upcoming SGNote 2. Time will tell.
So far 3 days on Blazer 4.0. All my apps are restored via TB and no issues with battery like I had on ICS. Don't really know what else to say. :good:

I'm getting 24+ hours on standby time. I have gotten about 18 hours with about 3 hours of screen time. Facebook and GBA emus. I wasn't able to do this since GB. I have done this by doing one simple thing. Turning off data. I kid you not. Utilize that data toggle. I know at first you're thinking no I need data. But you don't. Unless you're some business person, then this excludes you. Wanna check Facebook?
Also, wii benefit from something else. 4G WiMax. You can turn that on even though your data is off. You still get decent battery life since 4GWiMx knows how to sleep. Also, if you're driving around, it'll pick up 4G eventually (unless you don't have it) and it'll download what it needs to download. So by time it turns loses signal, you'll have your emails. I tried this and I still got good battery life.
Using Battery Monitor Widget, I was able to see that my phone wasn't "sleeping". That's what the main problem was. That's why I wasn't able to find any rogue apps using Better Battery Stats. But I did see my phone stayed awake. Like once my phone died in 5 hours. 10 minutes screen time. 6 minutes of deep sleep. Really? That means my phone was awake for over 4 hours!? Doing what!? No app was at fault.
Extra stuff. No need to read if you felt you read enough
An app you all should check out...
https://play.google.com/store/apps/...av_result#?t=W251bGwsMSwxLDMsImNjYzcxLmJtdyJd
Battery Monitor Widget (It's not just a widget. LoL!!)
It tells you how many #mA your phone is using. So if it shows 500mA. That means your phone is using 500mA per hour. Your phone has an 1800mA battery. So that means if your phone used a constant 500mA, it would die in 3.5 hours. This is a good way to see just how much power your apps are using, or if after 10 minutes your phone is actually sleeping. My phone actually started using 2mA. I haven't seen that since GB. I thought my phone would never sleep like that again. I cried.
P.S. If you get the app, in settings -> Calibration, change the battery amount from 1500mA to 1800mA. Apparently the app thinks our battery is 1500mA. Or maybe my battery REALLY IS 1500mA. I mean, it got my Nexus 7 battery correct. I didn't have to change it. I've always wondered why BMW said I had a 1500mA battery instead of 1800mA. I may have to look into. Wii all should probably look into that.
Also, those on Blazer ICS ROM. Using BMW, I was able to see something quite interesting. My phone would use a lot of energy. Like 1000mA just to send some text messages, or scroll through my app drawer. BUT, after I stopped using my phone for about 10 minutes, I'd turn it back on and BMW would show my phone gaining #mA, or charging. This means something is causing the phone to "drain", or show drainage, when there really isn't. The fact that the phone charges back means it never really used that much energy in the 1st place. But that only happens on this ROM. Since I figured out the data thing, I'm going to try CM9 again.

First off I want to say I'm not a noob when it comes to flashing. I usually get 14-18 hours on a full charge with 3-4 hours screen time which seems to be the norm on e4gt roms. I haven't reinstalled any apps since flashing the FK23 stock leak and now a few days into the room settling I have almost 4 hours on a full charge and down to 9 percent left with almost 2 hours screen time. I have checked to see if my battery is swollen and it's not. The battery stops spinning immediately after I let go of it. Screen shots are attached and any insight would definitely be appreciated. I may have to go back to blu kuban since that's been giving me equivalent if not better batter life compared to FK23 stock

Did you use One click odin to flash this?
Try removing unneeded stock apps

No this is from the tar file flashed in Odin 1.85 I believe... Had no issues for a few days now it's going crazy...I didn't even restore my internal and external sd backups yet as I wanted to test a clean install first

I'm having rapid battery drain, too. I used the one-click no-data. I want to wipe everything and start over. Can I simply download and OC the data, or do I need to do something else, first?

As far as I know (devs correct me if I'm wrong) you can just use the OC restore that doesn't say no data... But I went the extra step and copied my entire internal and external to my pc for safe measures and so I could pick and choose what I wanted back on my phone. Then I cleared my internal and external sd before I even one clicked so it was already clean... I just wanted to make 100 percent sure everything was clean but that's just me

Im not having any issues. Let your phone go dead tonight and charge it completely to 100% while off. Do not interrupt it until complete. Since I started doing this on flashed roms I have been getting better battery performance.
This is Dan's rooted deodexed zip...

I just did this while taking a nap and this is what I have so far after 100 percent charge and I restarted once to pull battery and look at it

Was it completely dead when you put it on charge? I don't know why this works for me, but every Rom I have ever flashed, unless something is wrong with it, gives me better battery life 3-5 days after I flash it. Some of the old-timers say a Rom has to settle for a few days, so maybe it helps do that quicker. If all else fails, reflash the Rom.

I gotta say that your drain seems pretty extreme! I myself am having slightly accelerated battery drain but its better than what I had on ICS. My best recommendation would be to use an app like ROM Toolbox or Titanium Backup to freeze apps and background processes you don't need. If that doesn't help you may need to look at other options.

^Thanked
I'm going to try installing GSAM and checking out what's going on in the background but as far as I can see nothing out of the ordinary is going on with the processes. On a side note when I took a look at my battery itself the sticker has pink X's on it. Not so sure if it's water damage per say but it may be condensation/humidity since I live in Florida. Looking into getting an extended battery as a replacement and any suggestions on the cheapest but most reliable battery to purchase would be helpful and I don't really mind if I have to have a larger back door on my phone. The cheapest I've found is a Trexcell with the back door for $16.99 free shipping. If anyone knows of anything better/cheaper please point me in the right direction.
Another issue I've been having is wifi will connect and reconnect uncontrollably whenever it feels like it, and the sprint connection optimizer was disabled since I Odin'd.

Ya GSAM is a must have. I run it on every one of my devices. I was also getting some irregular battery drain. Then I looked at what apps where keeping my device awake the most and found that hotmail app had a 4 hour wake lock! Ouch! I uninstalled that and setup the default email client to check my hotmail hoping this will resolve my issue. But I can tell you right now nothing else is keeping my device awake that long so in theory this should solve my issue. You may want to go through this same exercise. After a couple of hours of running GSAM looking at which apps are using the most power. Then switch your view to "Time help awake" and see if something has a wake lock holding your device awake.
Good luck

I re-read garwynn's instructions for the one-click and realize that I made a mistake going from ICS (Lightweight) to FK23 without a full wipe. I thought I was paying closer attention when flashing, but I screwed up. Thankfully, this should be easily fixable. I'm running the one-click restore and am optimistic things will be better.

Well after installing gsam I was able to see that after going from 77% to 15% in just over 4 hours with 1 hour screen time I noticed that media server had 293 wakelocks with 1 hour of time held awake...might have found the culprit...will keep you guys updated as im sure it will help a few...just wanted to update that I switched to Universe JB to see if it was just that tar...apparently it wasn't seeing just as much battery drain

And now I also figured out that the media server was not the only culprit. The battery seems to be the problem after numerous tests returning results that the battery was only a 1175 mah battery instead of what it should be 1800 mah. The battery does not spin so don't always judge by that test alone. After deciding to put my OG Epic 4G slider battery in and take it for a spin these are the results I have so far with 300 mah less (1500 total) here is the screen shots below from a full charge
*EDIT * I'm now running blu Kuban FI27 and tested also with the stock 1800mah battery still dies rapidly and WiFi still disconnects and reconnects randomly

Averaging 10% loss every hour
I am experiencing roughly 8-12%, so averaging around 10% loss every hour with moderate to slightly heavy use. Right now after 5 hours & 10 minutes i am at 50%. I have Facebook & an Exchange email synced and was on a phone call for over an hour, have been texting a bit and using email, the internet & Facebook. I have removed Sprint ID, which seems to run in the background along with Sprint radio, Nascar, Yahoo Stocks & News, so that may be helping a little. Overall I think that the battery performance has improved for me.

I was experiencing some pretty bad drain but after letting the kernel settle for a few days and disabling the location services, I can easily make it through the day

My batter time stinks!
I'm also getting 9% per hour battery drain. I have a Tasker profile running which turns off DATA when the screen is off. Most of the day, my phone has not been in use and I'm still getting battery drain. BetterBatteryStats shows that a process called "surfaceflinger" (Android System) has used the most followed by "googlequicksearchbox" followed by Gmail. Partial Wakelocks report says "signalCollector.Scanner has a count of 4844 and "LocationRecieverService" has a count of 3411 with "LocationReportingService" having a count of 5625. However, all of these combined only add up to 2% so I'm confused as to what is burning my battery.

Have u checked to make sure your battery isn't going bad? Take it out and try spinning it on a table on both sides if it spins like a top its starting to bulge, bulging battery = bad battery

Just did spin test as suggested. The battery did indeed spin like a top on both sides. Just ordered a replacement. Has anyone tried one of the "Gold" 2430mAh batteries made in Japan and being sold on Ebay from China?
