Battery consumption on Froyo2.2

I just replaced my battery and noticed it doesn't go beyond 4 - 5 hrs. So I was wondering if the battery has an issue or something. Can everyone using Froyo 2.2 state their battery life, please, mentioning also your phonel type.
I use a Touch Pro 2 from Sprint, that is RHOD500.
Thanks for your responses.

First the TP2 from Sprint is a RHOD400.
Second, it highly depends on usage. Lots of phone calls? Browsing? Streaming video, etc? 4-5 hours isn't bad then. If the phone is sleeping 100% of that 4-5 hours, NO radios (cell, wifi, bt, gps, etc) then that's pretty bad.
I typically get 6-10 hours (again usage ^^). Mostly idle, 10 hours. More browsing, videos, phone calls... closer to 6. I try to stick near a charger.
The port is far from perfect. The battery meter is off, and there's probably some places where power management could use some help - but it'll never sip batteries like WinMo does. WinMo is doing nothing basically, and Android isn't so great on native devices batteries... so I'm not exactly surprised Android sucks my battery dry.

I've had my lady's HTC Desire running Android in no-sim mode for three days now. Looks like it might need a charge later today. I did a 40 minute stint using the GPS and a mapping program during that time.
Suggestion to OP: Keep the backlight low, and on a short timeout. Also, disable the high speed network when you don't need it. Especially if the phone hops between high and lower speed networks frequently. Also, the battery might improve a bit after a few charges/discharges. Is it an OEM battery or a cheap knockoff?

Twice as short as in Windows
I really love Android on my TP2 and I'm amazed how well it's running on it. Really impressive, the only thing I'm less happy with is the battery usage. Even on stand-by it lasts at less then in Windows mode.
I've been comparing it now for a few days: I can do at least 1 day with a charge in Windows mode (sometimes even 2 days), but in Android mode I have to change before lunch time and before dinner to get through a day. Even while doing more or less the same things. (Turning off WiFi, GPS, sync etc do not seem to save much).
So, I'm afraid that I can only enjoy Android while there is power outlet nearby. This is really too bad as I would simply love to get rid of the whole Windows install.

Well with no SIM in of course it would last days. One dev found our port could run 65+ hours in this manner...

C'est la vie, read above. Android will never, ever be as frugal with your battery like WinMo is. Which do you want, Android and crappy battery or WinMo and good battery? Choice is yours, no one is forcing you either way. Can't have both tho.

I've actually been pretty happy with FRX7.1 and battery life. I'm consistently getting 24+ hours with my usage (mostly data, some talk).
WinMo would easily go 50% more, but a full day is enough that I can forget to put it on the charger at night and not be dead in the morning.
FaluSeyi - If it's not direct usage I would check to see if you have GPS accidentally turned on, in my experience that seems to be the thing that kills my battery if I forget to shut it off when I'm done using it.

Blame the guy that changed the phone casing before I was given the phone. lol. The front says Sprint and under the battery cover it says xxxRHOD500.

I rarely use BT, cell and messaging are my regulars and of course data. wifi doesn't work, though I wonder if it ever goes off. That leaves GPS, which I think is almost always on.
Thanks, y'all!

Wifi works fine. GPS is broken to always on, read the FAQ. That's the reason your battery life sucks, you don't know how to read!!

The FAQ says something about getting a position fix, but I couldn't see anything about switching it off. How is that done? Or can't it be done?
The Desire ran 92 hours before it demanded a charge up, including the 40 minute stint on GPS + program with always on backlight. 10 month old OEM battery used daily.

It's a bug with our port. Once GPS is turned on/used, it is 'stuck on' until you manually turn it off. This bug is fixed in the new GB build.
You couldn't see how to turn it off? Settings --> Location & Security. Wow... from a native device owner, I'm kinda surprised.

New GB build? Nice news... I thought it was a dead project by now

Battery Issue ! Its the 7th Charge Cycle Now

I bought this amazing [As you all know how fast it is ] Galaxy Nexus and was previously using hTC Desire S[GB] !!!
I'm somehow not happy with the battery life and also the overheating of Nexus !
It is Stock[ROM + Kernel] + Root ! around 7th or 8th charge cycle !!
I did try out Cpu Sleeper App works like a charm but was facing reboot issue and that is why had to remove it !!!
See if anyone of you could help me overcome these issue ! or Is this really something for me to worry about !!?????
[PS: Please don't recommend me to change ROM or KERNEL ! Because I prefer to stay on Stock ! Also NOOO Overclockig !]
Check out the Few screen shots i took when my brain kicked me to !!!

We need to see the screen before this one(the one that lists top consumers of battery). To see if something is waking the phone up. Also, charge cycles and calibration are bogus. If anything, you would be using the phone less since you've finally set everything up the way you want and the newness effect has worn off. My battery life has been about the same if my usage pattern remains like it usually does throughout the day. It doesn't really look too bad, but the drops seem a little steeper than what I normally see. . Grab CPUSpy and BetterBatterystats. I'm on my way to work soon, but someone may be able to help you before I go on break.

the screenshots you required

Here we go
ok so calibrators and cycles are bogus ! I get that !
What about brightness ? Should that be auto or manual mode ??
And is Google Now causing issue ?? Because its not really useful to me on daily basis !!???
And any other suggestions your would like to share

I was gonna edit my post, actually. I've personally never fully charged and drained my battery for any of my phones(some people swear by it though). I guess if the readings are out of whack then yes. My phone got stuck at 85% for almost 12 hours one day, but I had did something which messed up the OS. Haha.
If you don't use Google Now, you can opt out of it. Brightness is a personal preference. I usually stick mine at 25%. Auto may take a hit on the battery, but I doubt it's anything to worry about. Just the common sense stuff. Apps that poll data in the background will drain the battery, but if they're properly coded, they shouldn't be a problem Running on 4G/LTE/HSPA with a bad signal will drain it more since the radio is trying to find the best possible signal. After a full day of use, what is your typical screen on time? 18 hours is pretty good if you're using it on HSPA all day.

ya honestly that doesnt appear to have anything wrong. What results were you expecting vs what you have? You have a lot of screen on time, that takes a LOT of battery to run the display and using it when brightness is high takes significantly more. Also it appears you have a couple long phone calls in there as well. As far as heat goes, youre going to have that on the higher end phones due to the gpu producing heat and oled displays produce a bit of heat as well, lcd runs cooler.

Weak/unstable/unrealible mobile network signal could cause the fast drain of your battery. I saw you have one bar of hspa signal in the 3rd screenshot.

Those graphs should be much flatter during idle periods. Something is keeping awake. If you're on jelly bean its prob Google now. It does it to everybody.

Actually 3G isn't really well established for Vodafone[or any other company] in India.Also there is a peak going upwards in the first image indicating charging and after having a battery life of around 20 hrs on My Desire S and screen on [appx.] 7 hrs , I'm very disappointed with Jelly Bean !! Also While googling this issue I found out that somebody sniffed the mobile wifi connection to monitor and found some app constantly exchanging packets which according to his test was the root issue for the battery drain !!
Edit:
]Ok I found the way to shut google Now !
I'll records stats for a day or two and get back Thanks Everyone for your time and help

In Google Now >> Menu >> Settings >> Google Now there is an on/off switch at the top. Depending on the ROM it's included as either velvet.apk or QuickSearchBox.apk but removing that would get rid of Google search I think.

Yeah. I think its actually part of search. Like I said, just opt out and you should be good to go. Keep us posted.

Never understood some people's philosophy on extending battery life.

I've read a lot of posts complaining about battery life, and other posts about users suggesting ways to improve battery life. I've read stuff like, disable LED, haptic feedback, lower volume, lower brightness, LTE turned off, underclocking, turning off sync, live wallpapers, etc, etc. To me a lot of people are crippling their phones. If your battery can last you 10 hours, that's enough because you'll probably be somewhere you can plug in. What's the point of being able to go for 20 hours when you'll probably have the opportunity to charge it before then? It's better to have and enjoy all the features.
Maybe somebody can chime in and give me their point of view.

I agree. I would never want to sacrifice a feature just to extend the phone's battery life. Instead I use a custom rom that has all the features (and more) and 12 to 18 hours of battery life.
Sent from my SAMSUNG-SGH-I747 using xda app-developers app

Part of the issue is a sociological thinking pattern between wanting "more" and needing it. Depending upon the type of lifestyle you live, sometimes, battery life is of dire importance to have if you're constantly migrating around. But I agree, some people who aren't in that sort of disposition go overboard with it.

I just bought a bigger battery :good:

I agree wholeheartedly. If your battery is lasting you through your day (which mine does, and more) then why try to conserve it?

Yea its funny stuff people complain their battery only lasts 20 hrs but yet they want it to be able to do everything a computer can do and more....
Sent from my SGH-I747M using xda premium

The only conscious effort i made to extend my battery life was to undervolt the CPU a bit, but this was more for the lower temperature advantages with extra battery life being an added bonus. Beyond that i turned off things i dont use like BT, no need having something running that i have no use for. Overall i was happy with the stock battery except for any kind of heavy video or game usage which drains it pretty quick - solution : bigger F'n battery :highfive:

i agree that some people seem a bit obsessive about it. but we shouldn give bad battery life a pass either. hopefully we will see some sort of advancement in batteries to have better battery life while keeping them at a decent size.
i was kinda worried id have horrible battery life with the S3 being that its LTE. my last LTE phone was so bad it would die after 8 hours idle.

I keep the brightness to the lowest setting anyway, but I do all of this because I go to school fairly far from my home, and I'd like to be able to play games on my phone without wasting 5% battery every 15 minutes. I haven't switched power saving off since I bought the phone.
Stock ICS on my S3

I bought the extended battery because I like playing games from time to time and I don't want tl have to worry about my phone dropping 15% after playing something for 5 minutes. Like someone else said earlier. It really depends on the kind of lifestyle you live. I for one don't mind having the extended battery on my phone but I do miss how light it used to be.

How heavy is it? Does it fit in a case?

For me, and I want as much battery life as possible to avoid those situations where there is no way to charge you phone even if that only happens 1 a month or less.. As a parent I can't just let my phone die on me... I always need enough to be able to take or make that important calls/text. My goal is to have at least 20-30 hours of battery life per charge.
I think the only major feature I've given up is live wall paper. Other then that, it is just disabling other unused apps like gtalk, talkback, Google bookmarked sync. As well I've uv my phone as much as I can and run a 1350 max clock speed. I really don't see any major dip in performance as long as you do it right . I do use Tasker to disable syncing globally when the screen is off and make sure it automatically disable bluetooth after 10 mins once it disconnect. Also I have the Y5 app to automatically toggle wifi based off my network location. The most useful battery saver I've found is to set my wifi to only connect when the screen is on. Seems kind of backwards but it works well when very little data is process during idle rather the the phone requiring to keep a constant connection to wifi.

I'm also one of those people that closes an app as soon as I'm done with it. Use an app, press the home button, release and hold home, swipe the app away, sigh in relief. An old habit carried from my S2 Skyrocket, where getting 8 hours on stock was above average.

I have my screen brightness at 40-50 auto off.. i cant imagine turning it all the way down like alot of people say.. even when auto brightness is on it look very dull and dark at night to me.. Same thing for my tv with auto brightness.. but i still get good battery life. I am fully charged at about 6pm i use it till bedtime and use it for my alarm.. get up 4 am and when i get home at 2pm its still over 40%.. only thing i do is close all my running apps by holding home button a few times a day and same with ram

I work in an office so it's plugged in for the 2 hours before I leave so I have everything on full most of the day (brightness, lte...). Also, by undervolting I'm getting 30% more battery.
I think tips on increasing battery life like turning off lte and brightness are for people who can't plug in throughout the day or for emergency situations when you want to get the most out of your phone because there's some reason you can't charge.
Sent from my SGH-I747 using xda app-developers app

I get anywhere from 12 - 23 hours depending on whether I'm at work or off. I can live with that...but there are situations where being unreachable poses a problem.
So, to deal with my phone addiction, I got an original replacement battery. Always have it charged and on me. When the phone shuts down, pop in the replacement and your done. About a minute without a phone. This way I don't have to UV, worry about brightness, WiFi, Bluetooth, etc...
I can't deal with the bulk of an extended battery.

30% more battery by simply undervolting? I think that's quite an overstretched statement. How is that even possible?

Its not possible. Not by solely UVing. The sole purpose of undervolting is so that your phone dosent overheat when running high clock speeds. Saving battery is just a perk. You might save a few percent with the undervolt but nowhere around 30%. But don't take my word for it.....

Galaxy Note 2 Battery Life

Hello guys.
I've been reading these forums for a few months now and find it very very helpful in configuring my device. It's just now that i decided to sign up so i can be part of this great community.
This is my first ever post and i would like to get help regarding my battery life.
Ive read a few articles about battery saving and also from forums where people usually get more than a day's worth of battery life. That got me wondering why i only get around 8-10 hours average considering i only use it very lightly as im usually busy at the office. My actual usage time range about 60% of those 10 hours when i use the phone during breaks.
Here are example screenshots of my daily usage:
Here are some details about my configuration:
Brightness set to auto, most of the time at 75% level
Wifi, bluetooth, gps always off
Haptic feedback set to minimum
Mobile data always on and set to WCDMA only, area where im at is usually weak peaking at 2 bars of H and H+ signal strength
Gmail set to push notify
A few apps and widgets set to sync after every few hours(accuweather, flipboard)
Ive been considering getting an extra battery because of this but i really want to make sure first whether i could still do something or whether im doin something wrong thateads to the battery draining too fast.
So please if you have any more tips i could use, please help me out on this.
I thank you in advance.

Also here and additional screenshot to go with the two previous screenshots i posted. It says here ive only had the screen on for 3 hours.

Their battery lasts whole day long. It means that they get 10 hours of screen on time only. Not 24 hours.
Sent from my GT-N7100

Yeah. But in my case the 10 hours is the total life of the battery from the time it is charged until it dies. I'd be lucky if i even get 4 hours screen time out of it.
Do you have an idea why this is so?
Im guessing its because of the weak signal where im at and the fact that i set my phone to search for WCDMA only. Although im not sure whether this is really the culprit. I'll try setting the network mode to auto for now and see if anything changes.
Sent from my GT-N7100 using xda premium

Looks like it.
Try better battery status.
Sent from my GT-N7100

Well after i changed it to auto it improved a bit. Its currently at 14% after 11 1/2 hours with 4 1/2 hours of screen on time. The phone stayed on full edge signal for most of the time (which kind of sucks because internet became painfully slow on edge).
But still, i think this is far too short when compared to those who can get it to more than 24 hours battery and more than 10 hours of screen on time.
Is it possible that i have a defective battery?

Do you have locations services and etc (all 3 options) checked in the maps settings?
I don't get near as good battery life and my phone spends a lot of time awake. This appears to be do to google maps constantly updating my location. I would turn this off, but then i would loose google now functions.
Any help would be great.

I have only two of them checked(Use Wireless Networks and Location and Google Search). I have GPS disabled. i only turn GPS on when i'm traveling to an unfamiliar place which is not too often.

i got exactly the same problem, whats your firmware?
since i updated the phone to 4.1.2 the battery drains alone, every 8 hours it discharges 25% without using the phone, i am lucky if i get 5 hours of screen. The android os is the one draining all the battery in my phone. On 4.1.1 i could get 7 hours of screen time with 20+hours overall.

i got 4.1.2.
I can't compare mine to 4.1.1 because when i bought mine it got updated to 4.1.2 after a few hours.
having to charge at least two times a day really negates the otherwise great features of this phone.
I really hope we figure this out. I'll try UtkarshGuptas suggestion using Better Battery Stats and let you know what i find out.

I did they and found Google location services is the culprit.
I'm am referring to the locations services found under location setting in the actual Google maps app. I believe turning of location reporting may disrupt Google now features. Google locations devices is reading out as the main reason for nine consistent partial wake locks on better battery stats.
I'll try turning these features off and awe how it affects battery life and Google now tomorrow.

Please let us know.

after doin some tests with bbs i found the wakelock is mhl_wakelock,

First off, forget all the battery programs. Factory default your phone and add an apk at a time and use. You'll be able to tell what apk is the problem with a lil testing. Slow process yes but pretty straight forward and to the point. I do have a Note 2 and have no battery issues being rooted and having tons of programs, etc. Basically, I use and abuse my device as per my job and still get a day and a half out of the battery.

People who can get 24hr coupled with 8hr screen time most likely have their phone on low brightness and on WIFI not data.

I got a new battery and its still lasts the same as the other. Yeah it may be because of the mobile data always on that eats up my battery.
Problem is my data connection is my primary internet source i dont always have wifi hotspots. So i might just have to live with the short battery life or learn to turn off my data when i dont need it.
I'll still try looking for other things that contribute to the battery being drained though.
Thanks everyone.

I have GPS disabled, auto brightness (but fairly high level) and that improved battery life quite a bit. I then changed kernel to NEAK kernel, reduced the voltage levels for the CPU and that further improved battery life. I can get a full 24 hours on one charge and with normal (?) usage). With the new kernel I can also modify the charging current to a slightly higher level which reduces the time to bring to a full charge.
All in all not too bad but to expect more than 24 hours is unrealistic in my opinion as it is a big handful of electronics!

Not sure what you guys are are doing different. This is my first full month with my note and the battery is a beast. GPS is enabled at all times but all other syncs are disabled. That's just from previous experience. Sync will always drain the battery. So mine is off. I went as far as removing all the extra chargers around my office and home. .now I only need one. And I alsi don't see a need for an extended battery unless I'm going to be away from civilization for a few days. By the way..that was the only time I've killed my battery..kinda. see screenies
--I forgot about brightness- mine is set to 50% and 4G/LTE ..if the device is always searching for it, it will kill your battery. I turn it off at the office as much as I can.

I get between 6-7 hours of on screen time on mine.
Using dark backgrounds really helped the bettery life for me. I use a dark wallpaper for touchwiz, whatsapp, and also carbon as my twitter client.
Using Perseus kernel also helped because it doesn't ramp up the cpu as high as the stock kernel.
Wanamlite rom.
Brightness set to lowest at home. 25-50% when outdoors.
Two MS exchange emails set to push.
I use wifi all the time unless it's not available I switch to HSPA+. what a waste of a paid data plan
Google now disabled because it's a battery hog. location services kept on though.

LG G4 - Pitiful battery life

Hello all,
I recently purchased a LG G4 Back In July , on Verizon, switching over from A Galaxy Note 3 (Tmobile). Honestly I really really like the phone, but I think the battery life is pitiful for a $700 dollar "Flagship" phone. I mean not once has it ever lasted the full day. I had to buy a spare battery kit, with 2 batteries, and days when im out from 6am to late at night, I go through 2 batteries, and have to put the 3rd one in. I mean , this is simply unacceptable for a phone like this.
Also, the camera is excellent WHEN it works. A lot of times, it doesn't take the picture right away, there is a delay, and many times it falls out of focus. This is certainly not the high quality camera they advertised.
I am hoping there is a way to fix these 2 issues, mainly the battery issue though because it is awful in my opinion. Is there any tweaks or fixes for these issues?

You've barely given any relevant information other than how unhappy you are with the device, so I would suggest that you elaborate on that.

You could inform us if you're a heavy/light user, if you keep NFC, LTE, Bluetooth, Syncing, Wi-Fi, on during the whole day or maybe if you are used to 100% brightness display. Maybe you should check in your settings what is draining your battery and provide us the info.
I'm having a pretty good experience with the phone so far. It surely lasts a whole day with 3:30 to 4h SoT. I don't even need/have a spare battery.

One person having an issue doesn't mean it's not a great camera. You'll find it's likely still the best flagship camera of any OEM.
Battery use is so dependent on which apps you run, which mods you have, how often the screen is on, what brightness, signal strength, wifi, bluetooth, etc etc etc...

I came from a galaxy s3 and reckon the battery on g4 is awesome. I use it solidly on internet for 2 hrs a day (to and from work), check messages etc through the day, usually internet at lunch. And then evening time check facebook etc over WiFi infront of telly.
I unplug at 6am and plug in around 11pm with around 3% left. I bought a 2nd battery and only needed to use it twice. It has to be how you're using it.

13 hours on battery for me today and still 71% left. Light usage but it does illustrate that the battery life can be excellent.

of course, you can get excellent battery life on every smartphone - just put it in aeroplane mode..
I get MAX 3h of SOT time on my G4 - this is with fixed brightness at 65% (at all times) and only wifi and 3g enabled (NFC, bluetooth and everything else is turned off all the time)
to be fair I have yet to own a smartphone that lasts me more than 4h SOT..
the thing that annoys me the most is the broken knock code used to unlock the phone - it works 20% of the time at best
its a completely broken feature LG has not properly addressed since launch of the device (I am on V10e software)

There have been numerous firmware updates since. Have you ever performed a full factory reset after getting those updates ?
If the answer is no, then this is one potential reason for poor battery life. What you could try is to clear the system cache in recovery. Note, i said system cache not apps cache. Idea here is when updates come in there could be conflicts and it causes the system to work harder. clearing system cache might help, if it does not then the only option is a factory reset and then a manual install.
not restore. You install apps in batches, monitor, then install more and so on. You can restore contacts etc. but apps themselves will have to be reinstalled. Sometimes apps go rogue and have to be reinstalled. Its hard to tell which app is causing the issue. Otherwise you could just reinstall whatever app that seems to be taking up more than it should be.

What are you doing on your phone ? mention apps.
How do you access the net. How good is your signal. What are you doing when you access the net.
Also, the camera is excellent WHEN it works. A lot of times, it doesn't take the picture right away, there is a delay, and many times it falls out of focus. This is certainly not the high quality camera they advertised.

What types of shots are these. It can happen with portraits some times. It will focus on the background behind the person instead of the person and the face becomes softer and the background very sharp.
For this set focus little above the chest instead of the face. If they are wearing dark clothing this will cause other issues so focus on something else at equal distance that isn't dark.
Always check the shot at the pixel level soon after you took it. Rather than at the end of the day.

Just to clarify: I had everything turned on for those 13 hours - wifi/data/bluetooth/GPS. I also made 2 phone calls and did a bit of Chromecasting using the BT Sport app for a couple of hours. Or to put it another way, I didn't take any measures at all to preserve battery life.

I used to complain just like you're doing OP ( @dredmentia ) and fixed it all with a Zerolemon battery .
Is the phone bulky/no leather back/not easy to handle... , it sure is but if battery life is crucial then it gotta get fixed.
End my day anywhere between 7 to 13 hours of sot depending on WiFi or 4g and high CPU freqs, tried light usage and hit 3 days with 12 hours sot. Snap/insta/twit/fb/periscope/... Nothing kills this battery in a day.
When and if we get a kernel I'll move back to factory battery at least then I know I'm in control of how CPU works coz while optimizing the phone for wakelocks that's the only thing I have no control over...
As for now I'm just trying to burn thru this battery every day so I can charge it every night...
Last phone was a Z3 Sony and that really grabbed my attention with its battery life in stock form, almost too perfect, Almost.

This is what your talking about? Looks like a pretty nice battery.
LG G4 Battery Case, ZeroLemon LG G4 8500mAh TriCell Extended Battery + Soft TPU Full Edge Protection Case (Compatible with all LG G4 variants) (4897010519648)
It works with the USB charger that came with the phone ?

Did someone seriously just ask me if I kept the brightness on the screen at 100%???? Obviously im not doing that, im not some idiot. I know the screen eats up most of the battery. I keep the brightness extremely low way under 50%, or on auto., The battery still last a short amount of time. Its not acceptable

Then maybe something is wrong with the phone. I got also 4-5hr SoT.
It can't be just 2hr.
