Hi Everyone,
I am disappointed with the battery of Optimus One.
My Battery in Standby (GPS/Wi-fi/3g/Sync/Screen, ALL OFF and without USE ), does not last even 20 hours.
I have an application that shows what application is consuming more battery power and the "phone in standby mode" takes up 95%!
What are your experiences with this battery?
Mine has problems?
Thx
I bought it one week ago and the battery last one day with no problem (and it's not at its full "potential" since is new). When did you buy the phone?
I bought it 2 weeks ago
Using a custom rom you won't be disappointed with your battery no more...
I have openOptimus Rom with Franco kernel 15. I am at 85% battery after 14 hours. The phone has been pretty much idle.
Only 2G networks
Data disabled
Wi-fi on
Auto-sync on
Overclocked 480/729 interactive (interactive may not be optimal)
I'm using franco kernel v15.1 with devoid.franco, i'll try do update do devoid.froyo.final today.

Hi, what is data disabled? and how to put only 2g networks?
20 hours on idling? Send it back for repair/replace. Mine will last days if left idling (about 1% every two hours)
When I travel I turn all data connections off (Bluetooth, wifi, gps, data) and it lasts about 3days

Here are some potential things to turn off that might make the battery last longer. They are all in the settings app. I do not do all these since I find that some things might make the battery last longer but reduce the usefulness of the phone.
Setting/Display/Brightness
Setting/wireless & networks/wi-fi off
Setting/wireless & networks/bluetooth off*
Setting/wireless & networks/mobile networks/use only 2G networks*
Setting/wireless & networks/mobile networks/data enabled off* (I have this turned off all the time as I do not have a data plan.)
The items * I have off unless I am actively using them. I also overclock my Optimus. I think that this probably gives me a longer battery life, since it is running at 480 when I am not using it. I suppose if I was desperate, I would undercloack the phone (min 480 and max 480).
What version of Android are you running? 2.2 or 2.2.1/2.2.2?
When you click on Cell Standby, how much Time Without Signal does it show?
follow these steps and i think ull have what you want..
go to battery use and click on cell standby : then see time without signal. how much does it show ? if its above even one percent (unless uve mannually put ur device in airplane mode) i know the problem.
go to settings >wireless & network settings > mobile network > mark 2G only (if u are not using 3G) cause the cell might spen loads of battery searching for 3G.. then go to network operators and search for (mannually) and select ur own network provider.. like mine is airtel.. then let your battery run down totally.. completly to zero. then recharge your phone to full without any break.. this is called recaliberation. then see how much your battery lasts..
remember to turn off bletooth, wifi, internet, all ! while the phone is idle and you wont be using it for sometime. or, if you wont be doing or getting any calls or sms, consider switching to airplane mode..
you might be getting less battery if ur in a area with weak signal strength.. this makes the phone go wilder to search for signal. in these conditions, switch to airplane mode if you can . thatll save a lot of battery. and also during night if you want to.
dont hesitate to click the thanx if i helped !
EDIT: and ya every thing that the person after me 'Y.u.v.i' said.. though those are normal things and brightness level is most important..
and about francos kernel, ive had many f/c s with mik's cm7 beta 6.2.5 ..i prefer its own kernel , though dunno for other roms.. u might wanna try it.. ill try myself too..
yes ..few step here u can try
1.reduce ur brightness level to minimum ...
2. use 2g signal only.
3. turn off all extra connection like wi-fi , Bluetooth, auto sync , data.
4. use advance task killer and set it to auto kill app aftr every 30 mints.
5.automatic screen time to 30 sec.
6.if u r using custom ROM use Franco 15.1 kernal . and wipe battery after charging it up-to 100%
use thanks if u like my post ...
I did all the tips posted here. Let us now see what happens

I'm using 2.2
7% without signal.
Sorry for the dumb question (about 2.2 or 2.2.x) - I didn't read the first page carefully enough.
Try this: reboot, then enable airplane mode, lock your screen and leave it like that for about a minute, unlock screen, disable airplane mode.
Are you still seeing Time Without Signal? (of course, after a few hours, not straight away)
EDIT:
DON'T do any of the following:
- reduce brightness to 1%... come on, be serious! you really like squinting at the screen? screen brightness doesn't affect battery life that much anyway...
- don't use task killers! it doesn't matter if you have little RAM - it's there to be used. I will not go into details about this (there's whole threads about it), but trust me!
You could also try monitoring your apps with https://market.android.com/details?id=com.zomut.watchdoglite&feature=search_result and see if any of them start behaving wildly and keep your CPU awake.
Another thing would be to try Nessy Hypnos2... I had great battery life when using that ROM! If you're still experiencing the same battery drain with a fresh install of Hypnos, then I'm sorry to tell you but you'll probably have to send your phone for repairs.
I ended up recharging the phone two hours ago and it is at 91%.
Was 9% in 2 Hours - 4,5% per Hour. Very Bad...
...with nothing in use.
Only 2g networks
wi-fi/dates/sync/bluetooth ( ALL OFF )
Screen OFF (black, with -0% of brigth, because he is OFF)
I install Battery Monitor Widget that estimates my uses of battery in:
18h52m of Discharge (100->0%)
and 5h of charg in USB and 3h of charge inc AC.
I'm installing watchdog now, to see if have an App draining battery.
EDIT:
But I do not think that's because I have an application that shows the the CPU clock in%.
480MHz = 80%
729Mh = 20% or less
and another that shows the applications that consume battery
and Cell Standby = 90%

I tried and went back to get a signal instantly after turning off the airplane mode.

I got the same. My phone is also on the same settings, same rom, same kernel. Battery life was awesome some days ago, but now I experience average battery drain, I think I need to callibrate my phone as well. :/ I will do it probably after flashing void.final.

Updated my Mini to 2.1 from 4 days now-
Rooted using z4rot just to load setCPU.
2.1 in general is not so much different from 1.6, at least for normal user.
No significant performance improvement, no killer new functions. Just a "fine tuning work" in my opinion.
The bad come in just 2 areas.
1- Antenna reception.
Using 1.6 where I live I have a steady 3g network. Using 2.1 some time I discover that I'm under GPRS (i think the H icon mean GPRS, I'm voda so at least in Italy no EDGE network)
The antenna sensitivity is whorst than before...
2- Battery
Battery life is TERRIBLE using 1.6 I can go for an entire day (at least 8am-6pm)
Now in a few hours (4-5 not more) I have to recharge.
BT off, Wifi off.
Anyone experienced such decay of battery?
Can be the rooting process?
Any suggestion?
I have to try to switch off 3g but I dont like to use the slow GPRS so im not inclined in doing it1
H is HSPA which is 3G and others fast networks. If you had GPRS there would be G on your phone But i was confused too first time.
Battery seems same like before. I browse net, play games and listen music alot, so i need to recharge every night anyway. I'd guess some app eat it and maybe after some restarts it will settle. Synchronizing g-mail with phone ate alot of battery for me... but after a while its ok.
Ok, thanks for the H tips. So "H" is better that 3g!
Wow.
For battery life: yes I use google service so is always in sync
I think is one of the whorst design flaw of Android.
I like to be able to "open" sync in time I choose, for ex 10 min. in a windows of 30 min, ecc.
No software on the market do this automatically and ia polished way.
Can be set CPU causing more problem that the battery can save?
Disable Background data
Switch off Wifi Bt when not in need
then charge it when around 20% battaery
Doing this my battery life now is 2-3 days
Earlier with 1.6 it was 1 day max
wifi and bt are alredy off. background data?
turning that off is like to use a nokia of some years ago..
I depend on gmail etc.
intresting the tips of 20%, so you not charge at end of battery?
just when is arrived at 20%?
how it can have such effect?
with setcpu my battery now lasts for 20-24h, keeping minimal frequency at 122 and with ondemand scaling.
bt on for 2-3h, wifi on only when needed, sync always on but, the most important, only 2g. 3g uses a lot of your juice, use it only when needed. On 2g you still receiving emails and gtalk/tweets, and for an entire day. With 3g my battery lasts for 8h only.
ok, Ill give 2g a try.
Unfortunately Voda Italy has no EDGE at all...so if no 3g we are stuck using VERY VERY SLOW gprs.
i just use like 1:30 hrs of screen (on) AT 50%, i always use 2G network, background data conection like 2:00 Hrs, BT OFF, GPS OFF, WiFi OFF, All Syncronization OFF, some phone call (like 5 min per day), and i use set CPU to set the phone on demand between 122~600 MHz, with lucky i get 18 Hrs. of battery life...
Any advice?

I think 18 hours is Ok. Difference maybe is due to screen brightness; I use mine at 0%....
my battery last much longer with 2.1, i did a test, i put my phone in airplane mode overnight after charging it to 100%, unplugged the charger and went to sleep, checked it in the morning 8 hours later and it was STILL on 100%!
put it back to normal mode and the battery drains 1-2% per hour
Yeah,airplane mode is just the same with powering off,especially if you left it while you sleep dude...
Sent from my U20i using XDA App
I keep background data off and Data Traffic disabled and get about 1.5 days battery life. However, in Airplane mode, after 2.1 update, I have observed battery drains faster than 1.6.
^^ Use the Indian Firmware dude
its much better than flashed ones
Also charge phone when around 20% to get max battery life
Background data ON, Data Traffic enabled, live wallpaper (circuit board), Opera and mail one hour, BT 1 hour WIFI OFF, 1-2 hour call and sometime more.
24 to 32 hour Battery life.
I use Juice Defender and Set CPU.Battery charge when around 10 - 20 %.
^^Thats great
Calling for 30min decreased my battery life by 15-17% :O
My mini reboots every time i plug the in to charge, i saw there are some ppl with the same problem but i cant find a fix.
i did install the Nordic build.prop but repaired my phone when the update for my side came out. Can that be the problem?
I find the only thing now that really drains my Battery fast is playing games (Angry birds will drain my Battery in about 2-3 hours) otherwise.. if I don't play games my Battery lasts about 2 days. (up to a max of 3 days)
(I listen to about 3-4 hours of Music (over BT) each day, have Wifi on all the time I am at home, and use just a little bit of 3G when I am out (but I turn it off when its not needed)
Don't drain the battery to 0% this is really bad for Lithium battery's better to do top ups... and use USB to charge rather than the wall charger (lower charge rate will give you longer performance)
Run Launcher Pro Home screen replacement (I think its better than the stock one)
some software can really drain the battery fast, it tends to vary from person to person but I installed Nimbuzz and my battery went down like a sinking ship.
hope that helps..

When you say "Repaired your phone" you mean you put the build prop back to your old Kit code then Repaired with PC comp/SEUS? if you left the build.prop file as Nordic then you would probably still be on Nordic..
I ran nordic for a while and had no issues at all, then used Bin4ry's flash tool and a downloaded firmware to get my phone back to the correct Kit, I found it easier than playing with the build prop, its worth a try anyway..

Ok let me try explain .. i changed the build.prop to get the update but it did not work for me. So i downloaded Bin4ry's flashtool and software a flashed 2.1 on my phone.
I am on world generic (bought the phone in UK unbranded), when the update was availeble via SEUS i just plugged it in and did a repair, still with the same build.prop i edited.
I presumed it got flashed away with the repair i did
with the flash from Bin4ry an the repair from SEUS i got this reboot bug, so now i have no idea what to do next.
How do i know what kit i am on?

what Launcher are u using? i realize (maybe) that i replace the default SE Launcher APK with the Helix APK and seem to be a better battery life (because SE Launcher and Helix dont start together now).
Let's see how long this puppy can go without charging.
I'll keep its usage only to phone calls and messaging (which is a lot). It'll be my main phone obviously (and I can't turn it off).
Settings:
a) devoid. rom (link)
b) wifi, gps, 3g, mobile data - off
c) brightness @ minimum
d) auto-sync - off
e) underclocked & undervolted @ 480Mhz (min: 122Mhz)
f) governor set to conservative (still thinking about it)
g) hardware acceleration - off
h) watchdog lite installed (to check for apps gone berserk)
i) load monitor installed (to check for kernel loops and wakelocks)
j) airplane mode when sleeping or at classes, exams or hospital
k) red colored wallpaper (red is in the lower spectrum of visible light EM: higher wavelength, lower frequency, lower energy, lower battery consumption?)
Did I forgot anything?
unplugged
03h30m GMT+0, 12/01/2011
99% battery left
How about the Screen Filter???
LINK AppBrain
It's worth to use it also??
Regards Noein!
You really DO get bored!
You don't seem to have forgotten anything. I don't know if a red wallpaper really helps, since the big consumer is the backlight which you already minimized.
Good luck, I'll be checking this thread to see your record and I hope you are keeping track of how much talk time you get during this experiment.
What about ringtones? Are they on ?

i just did it to my phone.. but with the original stock lg rom. i set all settings to default , no wifi, no gps.... just calls and messages and a little use of mp3's about 1 hour.
the battery is 1%
and i have done 3 days and 2 hours.
1.31 hours of phone calls.
just when i need it..
i had unchecked all sychronization things, apps and i set it to gprs..
without turning off or airplane mode
the brightness was the default.
i thing it can be last longer..

Hmm, well the brightness is already so low :x
Anyway, I have to restart the test.
Underclock and undervolt seems to consume more battery...
I'll unplug @ midnight of 13/01/2011, GMT+0.
Keep us posted.
I've made a Test with Javali, using the LG P500 just for Calls and SMS, and after 48 Hours i still got 60% of Battery.
14 hours ~ 94% battery, without underclock/undervolt or using airplane mode.
i had cpu tuner and it respond so freaking slow...i wanted to save battery but instead ive managed to drain it more faster....

Intresting results, not bad for a smarphone! How would you rate your device responsivness do, was it realy sluggish since you undercloaked it?

I didn't underclock it.
I did at first but consumption was higher so I put it back to 600Mhz and restarted the test.
So, by extrapolation, we can assume around 6 days of battery life. Still, without knowing the talktime this is inconclusive.
@Noejn
What about undervolting keeping the same Mhz, is that possible?
@
I never tryed draining compleatly my battery because i keep on pluggin it in my computer to test stuff, but I would be happy if my phone could last aprox. 4days.

I read in this forum that you don't have a lgp500. Then how come you are testing its battery and other things.

Hi there.
So I flashed Cyanogenmod7 to my Optimus One
I'm very happy with it, however, there's a problem
On official froyo and 2.3.3 official gingerbread, i had the data connection ON and wifi on,too.So whenever I left the house, it would switch to data.And it wasn't on 2g,it was on HSDPA. Anyway, the battery consumption was barely noticeable,especially in standby mode.
However, if i do the same thing now, on CM, the battery drain is enormous
Wifi does not consume a lot, but whenever it switches to mobile data, the battery consumption is 10% / HOUR in IDLE mode, using the Smartass governor 245-600MHz, making the phone useless. And this is the consumption in standby mode...when I use it it's a lot worse. This problem makes me unable to use the mobile internet without returning home with a dead phone.
Is there a fix for this? Does anyone have the same problem?
Yes, i have the latest version of CM7, for my model,p500. Is it because of the old baseband?
Thanks in advance for any help
i encountered this for the first few days when i flashed to CM7 too
battery drop so quickly even when its at standby mode for 8 straight hours.
but after using for weeks, the battery begun to last longer, can last up to 2 days with light usage (some texting and tweeting)
im getting minimum of 4 days battery on cm7 -.-
Try this
1. Charge your battery to 100 percent.
2. Reboot into recovery and wipe battery stats.
3. Completely discharge the phone till the state it switches off.
4. Charge again.
Maybe it will help.

@OP: Which CM7 version? What kernel?
This is not usual.
I'm getting few days with CM7. Try calibrating the battery with Battery Calibrator from the market.
I already calibrated with the app from the Market
Charged to 100% ,Calibrated,discharged to 0%,then fully charged.
I did this twice.i dont think this is the problem.
I did a test :
Yesterday,when I first saw the problem,i had data enabled.I got 10 hours of battery life with the phone Idle (locked,yes.)
Today, i didn't enable data.I had 99% battery after 2 hours of idling. I guess that's normal.
So, i already know the problem. the data connection does this to the battery,but why?... as i said,when I was using the official froyo and gingerbread,i had both data and wifi enabled and i had absolutely no problem with battery drain...

This is called battery calibration.Whenever u flash a new rom,u need to calibrate ur battery so that it wont show u the stats of ur previous rom.If u dont wipe battery stats,sometimes the phone may switch off fue to low power at 15-20% or strange things like virtual increase in battery % by 2-3 %.So it is required to wipe battery stats,so after booting the phone,a new battery stats file is created and it wont give false info.

There's no need to completely discharge a Li-ion battery, it can in fact damage the battery.
Proper steps:
1. Charge your battery to 100 percent.
2. With phone still plugged in, reboot into recovery and wipe battery stats.
3. Reboot phone
4. Wait for phone to completely boot up then unplug.
5. Calibration complete

I checked for apps that consume internet.I don't have any.Facebook would be one,but that's all.
I read something about the older versions (official ones) of the firmware using something called NETMGRD to reduce the battery drain caused by the APN being on..
what do you guys think about this?
And also,since you asked about the kernel :
2.6.32.42-franco.kernel.v18
Cyanogenmod 6.5.8
If i use 2g continously i get batrey lyf of 3.5 hrs..
Is this normal?

I get good battery life using the 2x Battery program that cuts off the 3G data when the screen is off and opens it at a set time (every 30 mins on mine) to check for email etc instead of constantly when the screen is off.
One of your major killers i see is the constant WiFi, with it and GPS if your not actively using them turn them off.

Forgot to add, the rule of thumb is anything that uses a hardware component uses battery power.
GPS
Wifi
Cell Radio (2g,3g,Phone)
Screen
Vibrate motor
Speaker
It takes power to make those work so the less you use some of them the longer the battery lasts.
Anyone that drives at night knows the effect of turning on the wipers, the radio, the lights and the blower fan on high to clear off the windshield and seeing the voltage gauge lowering from the heavy voltage draw.
The reason i start this post is to gather experiences and facts about Xperia P's battery life.
Sony was advertising that the compination of Novathor and Whitemagice results to almost 50% less need in power energy for the mobile and for that reason the battery of 1305 mAh is enought.
My opinion is that Sony has ultimately failed in this part.
My phone:
Rom : 6.0.B.3.162 (i dont have the signal drop problem)
network : WCDMA (3g)
Data: always on
Ayto sunch: Always Off
Live Wallpaper: No
Battery life: 10-13 hours
I usually use my cellphone for calls / texting / whatsapp/facebook. The thing that use my battery the most is always Display (always 60%-70% of battery) and the hour that the dispay is active, is 1h 30min to 2h 10mins. The average talking time per charge is 30m - 50 mins.
I usually charge my phone twice a day but if i use it for games or internet or photographs i have to charge it three times per day.
I m waiting for the ICS in order to see some battery life improvement . If i dont , then i ll sell it.
my battery drains 3% per 11 minutes on standby 3g / wifi on (with profile set at max 200mhz on screen off)
Can you please post your battery usage screenshot?
Sometimes even when the screen is off the phone stays awake due to some apps running in background. Generally battery monitor apps causes such problem. I have autosync on & network mode as WCDMA Preferred/GSM and use WiFi a lot though it is not always on.
For brightness as soon as I enter home I keep it at 0% & when I am to go out I change it to auto. 0% has good brightness. There is a widget available for this easy toggle. Also check your WiFI policy. Apps like VIber have tendency to keep WiFi always on even though you have kept the WiFI sleep policy.
I agree the battery is not that good but mine easily gets me through the day inspite of gaming, always Whatsapp on, Viber online & Facebook.
Note:- I have kept auto retrieval off for Facebook & default email client though notifications are on for Facebook.
Make ur phone root first than see wat ll happen after makd root battery life ll increase and u can control ur applications. If u need any help reply......

I have my phone for 3 days, an offer from the wife, no warranty though but the phone is like new. I'm considering selling it because I'm experiencing the exact same issues as you, charging the phone 2 or 3 times throughout the day is ridiculous. Had an iPhone 3GS and wanted to update my phone and migrate to droid. However I feel very frustrated about all the crap always running on the background, have 'easy task killer' and even killing apps then end up popping after awhile. I know I can solve this by rooting the phone but nevertheless I find myself always having to manually turn on/off wireless, 3G network, apps, etc... This is annoying and stupid, the whole purpose of a smartphone is to use its features, I find that although this phone has badass stuff (like HD camera) they are useless if one can't use them...
I'll try to fix this issue on the next couple of days if not I'll just sell this, go back to my old iPhone 3GS which with the same usage, wi-fi always on and 3G lasts a full 12hour day (at least) and save some more money to buy a 'decent' one like Samsung S III.
Thanks for your post, I thought my battery had issues and the more I read the more I understand SONY f-ed up!
I bought this phone in September and m very disappointed...my huge problem is the battery life which is awful...i can't compare it to any other phone that i had before ... it sucks...is there any way to make it last longer ?custom kernel ?anything ?Never had a phone that bad (

Auto brightness, turn it on. NFC, Bluetooth turn it off. I always suggest that users turn on extended standby mode but some people want their whatsapp or email to come through instantly all the time which I can understand but it's a real life saver for me, I personally don't have a massive issue with my battery, lasts a whole day, sometimes less if I use the phone heavily.

The autobrightness is on, and nfc and bluetooth are always off (since i don't use em)...I need my e-mails, and Whatsapp is not even installed on my phone..turning 3g off or enabling the extended standby mode is like ... hmmm, i carry a 4 inch useless device around ... (

Your emails would come as soon as you turned on your device anyway could you screenshot your battery usage please?
i don't know how to take screenshots
i understand that the e-mails arrive as soon as i turn the phone on, but this is not ok...it will become a habit to look at the phone ....
Very easy to do, hold volume down and the power button

I think there is also a problem with reading the actual battery level (hopefully not hardware). The other day mine dropped from 15% to 0% in 10 seconds. This has happened a few times before when the battery gets around that level.

Try disconnecting your battery then, hold power button and volume up till you feel 3 buzzes

i have to root the device and to be honest, i am sick of it ...
attached screenshots...bare in mind that 3 hours the phone was on 2G and the display was as dark as possible (unable to see anything in the day light)
You could use clockwork recovery to erase the battery stats as well. I don't think you need root for it.
You charge to 100%, reboot into recovery erase battery stats, unplug and boot normal. After that you let it drain on its own until dead.
I've read that sometimes it worked after the second calibration or something but i believe it might be user error.
I erase the stats every time I flash a new rom. ...
I am now on 2.3.7. ... Maybe is better

Battery stats doesn't do anything: http://www.xda-developers.com/andro...-battery-stats-does-not-improve-battery-life/
That is, it essentially holds the information displayed in the Settings > Battery screen. Nothing more, nothing less. Thus:
It has no impact on the current battery level shown to you.
It has no impact on your battery life.

I would advise you to update your phone to the latest firmware, it has better battery management... If you are rooted, you can try custom kernel like ThP or Sliding_XP and custom Rom based on stock... I used to get only 10-12 hours of battery life in 2.3.7 before rooting.. The steps I took to improve battery life are:
1) Root the phone, add init.d and build.prop tweaks or install a Rom that has tweaks like Brain_ICS or XPT's Vision Roms.
2) Use any custom kernel based on stock that are tweaked to give better performance and battery life, along with above Roms
3) Switch off WiFi, Bluetooth, NFC when not in use. Or better, use NFC tags to switch settings (like WiFi on only at home, Bluetooth on only in car)
4) Keep the brightness to the minimum setting when indoors and keep it in auto brightness when outdoors.
5) I live in an area which has better 2g coverage. In network settings, if you set the network mode to select only gsm, battery life vastly improves as there is no searching and switching for a 3g connection. Also I find that staying in 2g gives better network clarity. I shift to 3g when I require high speed browsing only.
6) I usually keep data connected with auto sync on and extended standby mode on. If you switch off extended standby off, you can last through the day but only if you reduce the amount of apps syncing and the polling time of each app. In my case, I have switched off syncing for Twitter, facebook, Google+ etc and sync only for Google contacts, calender and Gmail.
7) I also have automated the phone to switch to airplane mode from midnight to early morning.
By the time I get home from work, I have at least 40% battery remaining. On the whole, I get 22hours on average and I have got 1day 12 hours maximum from my Xperia P. And happy with my choice.

Forgot two things:
I keep all location services switched off and turn it on only when required. This prevents the Map app from unnecessarily polling for location and helps save battery.
And sorry for such a long post. There won't be a tldr.

Just had this weird experience, battery was on 1 percent then I rebooted my phone using power button and volume up, then my battery shot up to 28 percent

that was android normal problem....thats why developer making phone by using high capacity battery (motorola razr maxx) . By using 3000mAh battery also just give certain phone for 2 days (using galaxy note 2). Android jelly bean suck battery juice faster because of its f***** project butter (uses cpu and gpu at the same time). Now phone developer starts frustrated on android...hehe (from my speculation)
Android problem how?
Almost all smartphones last about 1 day. Don't blame the Operating System it's the same battery life in all smartphones. Blame the battery technology.
