I have a question regarding my battery life. Yesterday night at 10:00 pm i played +/- 40 minutes on games like Angry Birds and used my 3G connection for about 10 minutes. My battery dropped from 100% to 61%. When i didnt use my phone (just idle mode) @ 11:46 pm i wanted to check how much battery i had left today in the morning (10:00 am) ..... it whas completely dead 0% .... i have this phone since august but if i knew the battery life whas so crap i would have picked another device.
Is there a way to improve it ??? since i read in diffrent topics people can use their desire for 2 days without a recharge.
- Not rooted
- Froyo 2.2
The HTC Desire is a smartphone running powerful mobile OS and a lot of additional gadgets like GPS, ...
So comparing battery life is impossible.
You can get a battery life of a mobile phone/week if you use it like a mobile phone: No GPS, no data, no playing games, no surfing, just occasional talking. So the battery life is normal and good, compared to mobile phones.
But normally you use it like a smartphone, thus you use it daily, play some games, ... which results in a battery life of a few hours (navigation) up to two or three days (moderate use), with an average battery life of a day (heavy use).
However, one thing for sure: Something is wrong with your phone.
This dosen't mean something is broken, rather you use an app/setting, which causes the battery drain, so you did something wrong, you're the failure, not the device!
Playing a game drains the battery fast. The display is on, probably max. brightness and the CPU and GPU is working like hell. It also gets warm, so you can feel the increased power consumption.
In sleep mode however, it should consume much less than it did for you. Maybe 2% each hour.
So to find what app you've installed or what app you keep in the background running, install a program like Android System Info and take a look at the task list, CPU load should be around 10% if you wait a few seconds and do nothing.
Take a look at the running services (android settings, applications, ...) and check if you really need all of them or if an app is active which you don't use. Then don't force close it, only idiots do this, rather open the app and deactivate the service (like automatic updating)
Next option: Test the battery life again. Maybe an app crashed and caused the increased power draw and now everything is working fine again and battery life is normal again. Then it's impossible to find a culprit with Android System Info.
Also tell us what settings you've activated: GPS/Wifi/Data/BT/...
This is happening because, some process not letting your device to sleep..!!
All you need to do is type *#*#4636#*#*
and check the battery history ,you'll get to know which process is using your battery, and remove that application.

Brightness is already said to medium, i also turned of those life wallpapers and it still drains like ****. When i look at the battery status it says battery life is good. Maybe a application that is running i dont know, ill try to find it out. So far i have a few apps installed which i rarely use.

Thanks will check it out and see what it does now in idle mode.
Idle mode 01:28 pm starts now, will post results in a few hours.
Edit: It's 02:00 pm here and i already lost 4% battery, its 96% now , i did *#*#4636#*#* and checked battery status and it seems wifi is in full use 99.7%. I will turn this off but what about the 3G connection
Edit2: It's 2:24 pm here and the battery status is 92% now, i reveived +/- 4 emails in that time. I checked the status in battery indicator pro and this is what it says
Android system 37%
Mobile Stand-by 22%
Phone inactive 15%
Wi-Fi 15%
view 11%
nothing else......i am really lost now.
Is my battery damaged/broken ? .... how can i reset/callibrate the battery ? or should i contact the shop where i got this phone from for a new battery ?
don't worry, lots of people are having bad battery lifes, and angry bird drain your battery really quickly, so it is quite normal, especially on AMOLED desires.

Yeah i have AMOLED
PS: After 30 minutes without touching it the battery is still 92%.
you could install setcpu and set profiles to save battry life
Might try that.....but after 1 hour the battery is still 92%.....i guess wifi drained my stuff down all the way as i am pretty sure i turned that thing of last time.
i will do some more tests later....
Edit: After 1 and half hour the battery is still 92%, guess the stock rom isnt that bad .

Its not 5:09 pm here and the battery is now 91% (idle, not touched)....guess wifi what the bad thing on my phone.
Tested the battery last night and must say i am happy with the results
10:00 pm yesterday the battery whas 60%, today i looked back @ 11:24 am and the battery just dropped with 10% (3G is on), i didn't touch the phone since then.
Stock Rom / Froyo 2.2
The battery drain came from wifi
I wrote HTC about the battery and they just sent me a brand new one So now I have 2 batteries and I think I'm happy DD
You can check your battery usage with a widget called "currentwidget" (search for it on this forum)
Usually on SBY with radio ON my phone drains from 3 to 4 Ma and 2ma in plane mode. (sounds good with a 1400mah battery)
In heavy usage, it can go anything from 150 to 500ma (ie: playing game with wifi ON)!!
For nice graphics, try to install "battery snap" too.
From HTC themself:
“To also help with Battery Life you can do these steps exactly:
1) Turn your device ON and Charge the device for 8 hours or more
2) Unplug the device and Turn the phone OFF and charge for 1 hour
3) Unplug the device Turn ON wait 2 minutes and Turn OFF and charge for another hour Your battery life should almost double, we have tested this on our devices and other agents have seen a major difference as well“

A known problem with the new update of the HTC Desire to Android 2.2 Froyo is battery life. How users have experienced the change is highly variable. Several said that battery life has improved, some even talk about a major improvement. The others have had problems that the phone charges from a fully charged battery several times in one day. If you have experienced such problems, there are measures, some simple, others more complicated and time consuming. Below I list things you can try, the lightest at the top.
# 1 Look what it's drawing power. Go to Settings> About phone> Battery> Battery usage or enter * # * # 4636 # * # * on the keypad and look around a bit. Is there anything that seems abnormal, or any program that seems to be the culprit, uninstall simply the application and see if that helps. While you can uninstall applications you believe is in the background and drag the cream from the phone's battery. Some applications may slip into the "Android System" in your battery history.
# 2 Uninstall system control and task killers. Advanced Task Killer and similar programs do more harm than they help. It is unfortunately only to realize this and stop using them. Android is an OS made for having many applications driving on the background. The operating system puts himself applications you do not use the idle to conserve battery power. Different programs that measure your performance on the phone, for example, Task Panel never sets in idle and therefore system resources continuously. If you have such software installed it may be time to consider uninstalling it. More on why the task killers and Android do not go hand in hand in to read this article by Android developer Dianne Hack Born.
# 3 Clean your home screen. It can be a good idea to try if it helps to clean up your Home screens from various widgets.
# 4 Do a soft reset. Discharge the battery completely (not that the phone is turned off), turn off the phone manually, remove the battery and reinsert it, restart your phone and put it on charge. This may have some effect and provide an improved battery life. Such a restoration known as a soft reset and should be tested before you do a master reset (hard reset).
# 5 Do a "hard reset". Have you done all the methods above are still not noticed any major difference? Then it's time to do a master reset of the OS. HTC have said they for some users might went wrong during the update to Froyo causing poor battery life, and when it is easiest to do a reset to get to grips with the problem. Although Android automatically sync contacts in the "cloud" so it might be a good idea to make a backup of your contacts (Contacts> Menu> Import / Export). Note that when you do a hard reset resets the entire phone, including messages, settings, themes, installed applications, etc. These are not the contents of your SD card. There are two methods to restore your phone, do a google search on "hard reset desire," so there are many simple guides. After restoration, the idea not to install any applications you had installed before. Install the programs one at a time and not too many at once.

Hi everyone,
I bought my new Desire two days ago, and im noticing a really fast battery drain.
I had a Hero before, and although it had a smaller battery, i would charge it every two days.
When i check tha battery usage, i can see big percentages in cell standby, phone idle and android system. (Its where the percentages should be really low imo..) Things like display, bluetooth etc that were supposed to drain more my phone's battery have much lower percentages..
Maybe all this comes from the snapdragon cpu??
I also have 3g off, always on mobile switched off and brigthness to a really low level (although i think amoled displays dont drain the battery that much)
My battery will last one day the MOST..
I know that the new battery has to be charged a few times before it has its full potential, but i think that somehow battery is getting drained..any tips???
Thanks,
T.
I to have this same issue if anyone has any ideas on this would be great

You just need to relax
My Desire couldn't get through even one day of usage when I first got it. Several things contributed to this:
1. The battery is not fully conditioned
2. The device is new so I want to play with it all the time. I'd turn it on randomly for no reason whatsoever.
3. I use several widgets that requires updating just because of the novelty (ie, Friendstream, News, Twitter, Stocks, Weather)
Now, I go through about 60-70% charge per day which is fine by me. The only things that have changed is this:
1. The battery has gone though several recharge cycles
2. I only turn on my device when I really want to do something on it.
3. I no longer keep many of the widgets that requires updating and for those that I do keep, I make it update less often.
Eg, Updating your weather every hour is not necessary. Every 3 or 6 hours makes more sense.
Eg. Rather than having your Twitter or Friendstream widget on your homescreen, why not just have a shortcut that goes directly to the application and then set it to sync on launch? It's better than having your widget update when you're not even looking.
Also get an app like battery indicator to give you a numeric readout of your battery life left. My android battery indicator was in the red yesterday and complaining I had to recharge, but battery indicator said I had 12% left and I got 30mins more constant music playing out of it before I got to work and it was still on 5%.
when the battery is running low - you get a button to show battery usage stats.. can you get these through some of the widgets or a comparable app from the market?
almost every update is set to to once a day, or every six or eight hours...so i dont think that the updates drain the battery that much..
its just weird that the most battery usage comes from call standby, phone idle, or android system..
mine was the same, i found its due to sense & all the background updates. currently running helix2 homescreen & now I only go thru abt 50% battery each day & that includes 2 hrs of music each morning.

alright i know this seems stupid but remove all your task killers, i got rid of mine this morning and my battery has been fine normally by now i would have plugged my phone in for a juice up, but not today i had bluetooth on by accident all morning and by the end of the morning it was still at 70% yes i know it sounds stupid but it actually helps
There many interesting suggestions posted here and like most i've been absolutely hammering the battery on my handset simply because its a new and highly entertaining/useful device.
Here's some of my findings...
The battery/app usage screen can be quickly accessed by pressing the menu button on the home screen, selecting settings and "about phone". It helped me nail down some of apps causing excessive drain.
Much like the iphone and any other high powered smart phone, high screen brightness, wireless LAN, bluetooth, 3G and the GPS receiver all take its toll on the battery. One of the biggest drainers is the GPS receiver so use it sparingly, I initially had it on permanently for some of the maps functions but the battery was lasting about half a day! Sadly i've noticed the radio is also a bit of drainer, which is a shame because it makes a nice alternative to MP3 playback.
Data updates and notifications again much like the iPhone have a surprising impact on battery life so set them to manual or long intervals.
In summary, learn as quickly as possible to get the most out of your smart phone by balancing out the hardware and software options.
As a sidenote, I was previously an iPhone fan but this handset has really changed my opinion of how a smartphone should really be. The combination of excellent hardware, an OS thats clearly designed from the ground up for mobile use and an ever growing (open) software base, will in the long term win over Apple's over analy retentive ethos! Top marks also to HTC for their sense UI and application suite, it works on top of Android almost as if it was always part of the OS itself and I just love the integration of social networking features....leaves the iPhone in the dust!
I have noticed that Turning off the Data Connection helps a lot.
Last night I turned data off, before I plugged my phone in for charging. In the morning the battery was showing MAX power. Where normally in the morning would be 97%, because charging stops once the battery is full.
I am still experimenting with all the Apps & Widgets that turn data access ON/OFF, but my conclusions so far, just get a simple widget from the market, and keep data connection off, until you need it.
There is an app that turns data connection off once the screen goes off, but if you download something or wait for something to load and the screen goes off, data will also be switched off which is not what you need.
Hey all, I don't know if anyone has even noticed on their Evo's but on mine, the Android system usually eats most of the battery. I noticed there is a ton of processes under Android system that are running compared to like five on my Hero. I've never seen the core system processes take up more than maybe 15% of the battery, but right now, I'm at like 41% with 16m 6s of CPU total and 47s of CPU foreground. If anyone knows why this is or a way to fix it, please let me know. I'm on the first MR update. I've been able to get a lot of battery stuff figured out, if I can get the system to calm down, then I should be able to get even better battery life than my Hero.
I'm seeing the same thing, android system is at 96% battery use after letting the phone sit overnight. Never saw that on my nexus, this is strange.
Could be related to the fact that everything is syncing up, I just activated last night too.

Yeah, the system seems to have calmed down a bit today, though I also have the OC widget running to keep the processor lower during sleep. I'm guessing its helping, but I'm not sure if there is something else to get it down. I almost never even saw the System show up in usage on my Hero, now its one of the top contributers. I got used to having custom roms on the Hero, but so far all I need on the Evo is unrevoked. I know a lot of people around here don't like it, but I found I only needed a couple of apps that require root and so far love it. That OC widget really comes in handy.
maybe i can clear things up a little bit for you guys...what you see in the battery use section is distributed across 100% of the time since you last had it plugged in. if you notice all the percentage numbers add up to 100%.
if you plug your phone in and turn it on and off on you will see that android system is probably around the 90's thats because android system has used 90+ percent of the phone since you plugged it in....over time that number will lower, becuase other things will start using the battery power... what you see is a percentage based on time. not based on whats actually working RIGHT THEN AND THERE do you guys understand?
I too am having that problem and at 15% battery life warning - it still shows my Android system @ 40-44% usage after 8hrs of work.
I mostly text message all day long due to work - make phone calls and recieve calls from work every hour. GPS on for no more than 15min all day long to get direction when my keymap book doesnt help.
4g off, bluetooth off, background data 15 min only (gps) than off, gps off when not in use, mobile network (3g) off when not in use.
I would have figured my screen being on would have drained my battery life since I check text message every 10-15mins for 8hrs...
So went to work at 9am, 100% life
got off work 6pm, 25% life
I've done all the tricks, cdma only, force stopped a bunch of apps, goggle talk off, sync off, making sure maps/gps has been closed (forced or not)
still disappointed with battery life.
Unrooted Evo
My crappy AT&T Razr lasts me 2-3days with text message + call + 1.5hr of playing Bejeweled a day
*facepalm* you guys don't get it....

check your hardware version there is a thread about different types of evos and it seems like everyone who has the hardware revision 0001 has really bad battery life. i would exchange your device.
Yes we know, Freelancerx, or at least I do. But after over 8 hours and the system is still using more of the battery than anything else is a little disturbing. Never seen that on any other device. I have Hardware 0002.
I have this same issue with hardware version 0002. I run Fresh 1.0.1, i use Netarchy-toastmod kernal, have latest radio. I have also tried Damage Control (did get slightly better battery life out of DC but not amazingly different)
after 7 hrs since unplugged my andriod system is at 39%, cell standby 28% phone idle 20% display 9%.
i dont have bluetooth, wifi or 4g on. I use juicedefender+ultimate to turn off apn when screen is not on. I use set CPU to underclock when i am unplugged and go down to 128 when screen off and i am Stilll lucky if i make it all day with moderate usage.
Every day it is the same andrioid system is around 40% of the usage for the time it was unpluged.
the following is listed under included packages (not sure if this shows the same for everyone or if it shows what packages are running)
BRCMBluetoothService - Bluetooth is not on so if it shows packages running this may be an issue
Sync Feeds - I have all android syncs off and mail at 6 hours
settings storage
Rosie Utility
Acounts & syync
Account and sync settings
settings
HTC Widget Download Manager
Network Location
Setup
HTC Checkin service
Checkin serivce
VPN services
Android system
Wonder if there is something to the android system on these (ie something not turning off that should) or if we are all just crazy and happen to get the same results.
I had a hardware 0002 model and often experienced the same thing with high system % usage.
My phone was replaced, due to a screen issue, and now I have the 0003 model and seems system % is much lower so far.
I haven't installed any system update yet, so I am on the first original release rom (not rooted yet).
Going to be testing it for a few days before I update and root, so I can make a fair comparison between the original and current oem's.

I think everyone here understands this. the question i think we are trying to figure out is why with similar usage and configurations some people get 40-60% android systems usage while others get 10% over the same period of time.
Android system is way too high.

Yes but if it is configured in an optimal way then android system is always beneath cell standby and phone idle.
For example, today after 15h 28m 23s since unplugged I have...
Cell stanby 38%
Phone idle 37%
Android System.....12%
That is with background processing with auto syncing every hour or so.
I'm getting 4-5x idle consumption on latest JPA. Hope this is still not final..
I see that next version of Android is already trying to discredit previous one. Don't be afraid, gingerbread, we will update to you anyway =))
On a more serious role - I see approximately the same battery.
Re-calibrate your battery.
A bit worse on my end on IDLE, but same on usage, close to 8hrs of battery life watching a 720p movie.

Speaking of battery stats, a lot of people misunderstand this as the file that keeps the current charge of the battery.
my standby time of the battery is great. No drop in battery after a full nite of sleep.
however, surfing net on data really eats a lot, 1% every 2 or 3 times.. really fast

Maybe you just can't understand well the charts.
for example: Music Player 25%, it doesn't mean music player consumed 25% battery; This means that when music player was worked, then battery consumed was 25% - what did consume it? - The music player + display + some refresh + etc...
Yeah, I know a little bit strange logic for "Windows taskmanager" browser kids; but this technic is general in mobil IT (maybe Google should hide this feat, bcoz lot of users are confused; and ask again and again and again and again and again...)

I dont even think he is basing it on the battery chart usage, I dont think anyone does.. we are just looking at the battery indicator. If we idle for 8hrs we epxect no more than 2% battery drop.
I get 20% battery drop in froyo for 8 hours during the night without even switching the phone screen on once!
Maybe because of all of the services I have?
I have the following real time services:
1. google stuff
2. exchange (touchdown)
3. Tango
4. whatsapp
5. Chrome to phone
6. SMS Backup+ (backs up SMSs as soon as they arrive)
In addition to that, I have two email addresses configured in the stock email app with 1 hours pull time, and in "accounts and sync" I have facebook and twitter put as sync once a day.
I have a bluetooth headset connected all the time and receiving calls though it, I make and receive almost 1 hour of call, probably 5 SMSs, WiFi is on all the time, and the display is set to auto.
It is also worth mentioning that I have the JPA, OCLF and the 341MB ram kernel (250Hz) with the enhanced GT TWLauncher, no live wall paper, no auto syncing widgets.
My battery lasts almost 8 hours until it is flat, in which I have another charger at work, that a good 2 hours charge keeps me going until sleep time, where it is flat again, and then I put it to charge all night long.
If anyone is having my same configuration and settings, please share your experience.
Oh, I have disabled the haptic feedback completely and the clicking sounds universally also.

You are a lucky guy,
The first day I used my phone, I got a drop of 15% per hour of continuous use.

Charge the battery FULLY, & start discharging it, when it comes down to 5% or something, go delete the battery.bin (search the forums) or some such file. You need root. The restart, Viola, your battery is indicating the exact charge.

AFAIK, phone usage timer "in battery stat" is not increasing while the phone screen is off, indicating that phone is not operational.

I dunno what tango exactly does but i can only confirm this: tango kills the battery in no time. even the newest version claimed to be "fixed for sgs", it still eats 5% an hour in standby just by adding tango.
besides, tango doesnt work very good anyway.

I've read about that by deleting the batterystats bin file, Im still looking for a solid explanation on whats exactly in that file, from my own understanding its just a battery usage history.

how are you using your phone ?
I see a lot of these threads talking about battery.
But bottom line is - How do you use your phone.
You have to compare apples withe apples.
Only 1 person in this thread described how he / she is using the phone.
Thats something you can compare with
I usually have mine running for 8-10 hours and have to charge. (almost empty then)
But im a heavy user.
Blutooth headset - Wifi - Sometimes GPS.
Aways on fastest netvork.
Exchange and Google mail, facebook and twitter.
Everything consumes battery.
BUT having said this -
I was on a vacation in France, and stopped every service, as im from another country and did not want to pay expensive roming prizes.
The phone now lasted 2-3 days on 1 charge, and this was all new for me
You get the drift
Forget about this battery charge discharge / charge delete stats thingy.
It will absolutely not give you longer battery run time.
Maybe the battery indicator will be slightly different, thats all.
Not worth the effort.
Hope this helps you

I think I found this over on the Desire forums but these steps have helped me immensely. I did these steps just last night, and I unplugged my phone at 12am and now at 9am it's at 90%, with 3G turned on with syncing once an hour.
With your phone on, charge it to 100%. Once it reports it is full, disconnect the phone and turn it off. Plug it in again, charge it until it says it is full (1 minute or so). Then disconnect again, turn it back on, and plug it in again. Charge it until it's full. Disconnect.
I find that after I do that, the battery life improves IMMENSELY for at least a couple days, or until my next flash (still testing).

If you checked what you posted you can see Im all over that thread, bottom line is that doesnt work for me what works is I just charge to full while the unit is off. Thats how I calibrate it and it always works on my end.

Charge the battery FULLY, & start discharging it, when it comes down to 5% or something, go delete the battery.bin (search the forums) or some such file. You need root. The restart, Viola, your battery is indicating the exact charge.

Hi, I also have a question regarding recalibration. I have the OCLF v2 installed and find / -name battery<somethingwhatever>.bin shows me 3 files batterystats.bin (I'm pretty shure this is because of the oneclick lagfix). Do I have to delete all 3 files or is it only necessary to delete the "real" one?
my battery drains like a bugatti veyron doing 252mph constantly
so what would you advise . is the kernal i have now the best or should i change .. i dont want to reall lose much performance on what i have now but would like the battery to maybe improve if possible ...
from full charge taking plug out searching market for 2 mins the battery drains 5-8% in matter of mins
and i have only had the phone a week
With that kind of drains the problems the kernel won't change that much. There is probably a app that causes the battery drain so looking in to that will have more effect. Also the brightness/screen on is the biggest drain and kernel won't do much about that.
You said that you have the phone a week, the battery needs some time to reach it's full potential and you probably use the phone a lot because it's new. So use the phone normally for another week, after that week let the phone drain until it shuts itself off, leaf it off and charge it till it's full. (there is a different calibration method but this always worked for me)
What do you have now? Stock or rooted?

First of all, I would assume that you don't use the phone non-stop (it would be justified to lose power in a few hours if you're on it non-stop).
I recently had issues with power consumption as well. What I did was:
1) check the built in battery monitor: menu-settings-about phone-battery-battery use. The bad thing about this monitor is that it does not differentiate well the apps consuming power, but you can still see if there's something wrong, as the most consumption should come normally from the screen and voice calls. For me, the most consumption was made by com.htc.bg, which, if I let the monitor on for a few seconds, would transform in the calendar app. Weird stuff. I unchecked the calednar auto sync from menu-settings-accounts and sync. It may have slowed the power loss down, but not significantly. I noticed a significant loss of battery by WiFi. I realized, I needed more information so:
2) I installed an app called 'Power Tutor'. What it does is, it calculates which apps consumes power, and it shows you in percentages. After install, you need to start the 'power profiler'. It will appear in your notification bar. If you let it run, after a few hours, you can see in "view application power usage" who is using power. That's how I discovered that my winamp app was really off the charts using power like crazy. So I went in the winamp settings, and I unchecked some options that could have determined this power consumption, like wireless sync, automatic mount as USB drive, etc. There was actually an option that was overriding the wifi power management, stating that the wifi does not stop after 180 seconds of standby. Basically, if you have wifi on, and you stop using the phone for 3 minutes, the phone automatically turns off the wifi. This was not happening any more, due to winamp. So I unchecked all those options, and voila. It worked, I have now normal battery life.
Good luck!
be aware of a couple of things
1. battery drain for the 1st few weeks are high because of a couple of factors, the battery "learns" and gets conditioned over a period of time (doesnt use the old 16hr charge process). its a new device for you so its a novelty, you probably mess about with it with the screen on more than you think.
2. there is a configuration within HTC's builds and in the memory chip of the battery to stop over charging. the device will charge to 100 and then slowly deplete to 90% while still saying full on the phone. as soon as you disconnect it recalibrates to the correct value which is anywhere between 90% and 100% depending at which part of the cycle you catch it
Some other tips to increase battery life, from a friend of mine in the Romanian forum:
1) use the app watchdog, it will warn you when an app is using too much of the processor and will ask you if you want to close it.
2) juice defender with the paid add-on 'ultimate juice' - with the correct settings... it's amazing.
3) Dial *#*#4636#*#* - phone information-network type: select gsm auto prl. The phone will stay on 3G when it has good signal, and switch to 2G when it doesnt, saving battery
4) Change the wallpaper to a static one, not a live one.
5) Go to menu-settings-accounts and sync and increase sync intervals for weather, news, or even set them to sync manually when you choose.
i will try and answer everything at once ..
ok my screen is on 13% brightness
i hardly ever use my phone , the only real use was to root , s-off, put ROM ETC ON
I reply to about 50 texts ish per day and search the market for literally 1-2 mins to see what new apps are in
i dont play games or anything
the thing the battery uses most is the screen and as i say i have it on monochrome theme with 13% brightness, there is nothing synced , i check automatically for email etc .. actually beautiful widgets is set to auto update every 4 hours
i never use wifi as i have a 3gb download/data usage, i dont use gps ...well i do but i have had no need to .. thats about all i can tell ya
rastaman the pt2 is a bit weird it should stay at 100 if just taken out of charge
I calibrated the battery and that made no difference.

Hi all fellow forum members! It was about time to retire my old Galaxy S2, and i decided to buy a S4 Mini. About the same size, better specs and everything. But i dont like the battery life at all. I dont think its normal for my battery to discharge 20% over 8 hours at night. Does anyone have the same problem? I have been trying different approaches. I installed Snapdragon BatteryGuru, put the phone on power saving mode all the time, even switched 3G off, although without 3G there seems to be an improvement, but I'll let you know how's that going. So my concern is that i might have a faulty device.. or software.. idk.. when i had crazy discharge syndrome on my S2 i just changed the kernel and/or the ROM. Any advice or opinions on the battery life of the S4 mini will be welcomed and appreciated!
I don't have too many battery problems, I guess. My phone has been off the charger for around 10 hours - and the battery has dropped to 85% - which I think it OK. I've sent some text messages, checked e-mails, used WhatsApp and had a few phone calls, not exceeding 10 minutes in total. Oh, and the GPS is on 24/7 for now, but I've just got the phone rooted, so this will not be the case any longer. The phone says it still have some 7½ hours left - which wouldn't be enough for an "all nighter" tonight.
I have disables many of the push notifications, which might be the reason why I think it's a fair battery life so far. I used to have the SGS2 as well, which lasted around the same as this phone I reckon. The biggest hog is the Google Services/Framework that takaroundes up 25% of the battery usage at the moment.
I have though of having getting an extra battery for this phone, as it's always nice to have one charged.
My I9195 uses about 3% during night (7 hours, 3G data and wifi off). Try to use an app to see wakelocks used on your device, e.g. Wakelock Detector or Better Battery Stats - they might provide you with some hints to apps that keep your mini from deep sleep, which can cause the battery drain.

If it's an I9195, can you try to disable NFC and see if it improves?
My biggest drain is the screen. The device lasts about as long as my friend's S2 (we were playing a coop game together) and then surfed the net over 3G for a while.
We both scrambled to look for a nearby charging socket at almost the same time
Thanks for your replies guys! I will try those apps and report back. Wakelock already found one of my apps that has awaken the phone 1200 times.. shieeeeeeeet.. hopefully now that I have disabled it things will go better..
Hi all! I have found the source of my battery drain. It's Google location services. Turns out it's a common problem on android 4.2.2. I tutned off Google location an I my phone drained 2% over 8 hours. Sync, wifi and 3g were also turned on. There is a fix over at the nexus 4 forums, but it requires root and I don't know if it will work on our galaxies. If you have root, google nip wakelock fix, try it and report back.
I had battery problems on my s4. Turns out it was the SD card. Removed it and battery improved. In the end I had to change it for a new one.

Which one did you use? Sandisk 32GB?
I got an S4 mini for my gf with that card and it has terrible battery life.
The battery drained from 100% at 7 in the morning to 15% at 5 in the afternoon...
That's surely not normal...
Edit:
I noticed that the "media" service took up almost as much cpu time and power as (active for 1,5 hours) as the mobile connection.
I suspect, that some corrupt media files or whatever kept the service alive, which tried to scan the DCIM folder over and over again.
I checked the SD Card which was full of almost 5GB of old pictures pictures which for some reason couldn't be deleted because of "unknown errors".
So I took the SD Card out and put it in a card reader, to back up the files. Then I deleted the files, put the card back and formated the card.
Then I copied only some of the new pictures back into the DCIM folder... I'll see tomorrow if that helped.
Battery Drain
Hi iconata,
Can you let me know how to "disable" Google location services, which you observed as the source of battery drain? I believe I have disabled it but the battery drain issue still persists.
And FYI - the following is the message I wrote to Samsung and am waiting for their test to validate the result of my S4 Mini. Based on what Samsung told me, the Safe Mode calls out same phone settings as Factory Default, but it seems the following test cases did reveal different resutls from what Samsung told me...
Message to Samsung
-----------------------------------
Hi,
Thanks for advising to check battery under Safe Mode. The following is the 3 test cases I have done but I still have BIG battery drain issue with my S4 Mini.
All the test cases were performed under same conditions:
1. 3G on
2. Power Save Mode on
3. Standby for 8 hours overnight, from 12:00am ~ 8:00am
Test Case-1: All the extra apps installed
- Battery drain: 3% per hour (as I already reported)
Test Case-2: Safe Mode; long press volume-down key, with Safe Mode shown at lower-left corner on desktop
- Battery drain: 0.7% per hour
Test Case-3: Factory default settings; reset to Factory Default setting; all the data were deleted and no extra apps were installed; the phone was back to the original Factory default setting
- Battery drain: 2.9% per hour
Test Case-1 and Test Case-3 almost came with same battery drain issue at same drop rate, so those extra apps installed for Test Case-1 shouldn’t have contributed to this battery drain issue so significantly. However, looks like Safe Mode and Factory Default were very different, although you thought the conditions of the 2 should be same.
I still have battery drain issue even after rolling back to Factory Default Settings, and I cannot live with Safe Mode. Please help.

Hi pudin! You can turn off Google location services from maps app. Go to settings->google location settings and uncheck allow Google to use your location. And to further improve that you can turn gps off, and turn it on when you need to. Yesterday I decided to root my phone because greenify was asking for root permission and everybody was putting the good word for that app. Turns out it's a total croc... you can hibernate downloaded apps, but you can't do the same with pre installed. 0 use. Further more I started to receive an annoying notification that my phone's security has been compromised and it needs to reboot. Got angry, downloaded an official firmware from sammobile, preinstalled, turned google location services off and got this pretty decent battery life. Screenies are below, feel free to post your thoughts. Please note that I keep BaterryGuru and PowerSave on at all time.
Battery drain
Thanks for prompt feedback iconata! Now I can confirm the Google location services have been disabled on my S4 Mini. Also, I don't enable GPS unless I need it so those battery consumption numbers were tested without GPS running in the background. I got the call from Ssmaung tonight telling me my phone consumes more power than what they tested, so I'll return it to Samsung for further diagnostic tomorrow. Will keep you posted if any update.
BTW, I'm not that kind of guy brave enough to root my phone like you guys...
im having 3% battery drain over night
using 2 sims.
wifi off
gps off
powersaving off
Network mode: sim1 GSM/WCDMA (auto), sim2 GSM
here are the screens

ill repeat the test today from 100% battery and see
battery drain during standby
Hi,
Checked the image you posted and it looks like you were still doing something such as making calls and playing game over night. Your 3% power consumption per hour is similar to mine, but in my case Cell Standby and Device Idle are the 2 major items consuming the power the most over night, when the phone really enters the standby mode. Try to have your phone enter the standby mode without doing anything over night and check if the result is still the same.
strange thing... my battery was showing 16% left.. and went dead..

New FW update that improves battery drain
In coincidence I got notified of a FW update just yesterday night, one day before I sent my phone into Service, and it did improve battery drain significantly, from 3% to just 1% per hour over night after I checked the phone this morning. You guys may want to check the update as well, and I'll test my phone again tonight.

Which firmware?
I flashed the pre-rooted MG4 (over the stock MG4) yesterday, wiped the phone and froze all the samsung bloatware stuff.
That thing is still draining about 4-6% per hour while just lying around untouched. The phone is in power saving mode.
new test factory reset, all bloatware removed, just whatsapp is installed
screens
http://db.tt/nZFb2QKa
I still have 1.7% battery drain per hour I think is still bad
GMS arena seems to be the only site mentioning that issue:
Unfortunately the higher than average battery drain in stand-by mode prevented the Samsung Galaxy S4 mini from getting an impressive overall endurance rating. Even so it did more than well and if Samsung improves the stand-by time with future firmware updates, it might be one of the longest-lasting smartphones on the market.
