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).
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

Click to expand...

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 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.
Hi,
I watched my battery info a moment ago and don't know if those stats are normal.
Cell standby: 42%
- Time on 19h 44m
- Time without a signal 100%
Display: 20%
Android System: 15%
Phone idle: 7%
Android OS: 6%
"Cell standby" seems to use much battery power and my phone signal strengh does not show more than 2 of 5 "bars" in the notification bar (inside buildings). Data network is not enabled.
Now I'm not sure if the antenna of my phone might be defect cause of this high battery usage. I am also sometimes not reachable if people try to call me.

But you miss the key component battery used in that time span .
1% battery used 90% used ???
Your post reads as phone not receiving a signal .Phone sleeping/not in use .
Of the battery used in that time 42% was cell standby NOT 42% of the battery 42 % of the amount used .
more than 2 of 5 "bars" in the notification bar (inside buildings)
No network will guarantee any reception inside buildings . Faraday cage and all that .
Test the phone outside the building first for signal strength .

Cell standby
If you know you wont have signal turn airplane mode on, to save it from searching for a signal all the time, and thus draining some battery.
@Jesmicael: Thanks! I'll watch this thread.
@JJEgan:
My phone uses about 12% battery within 9 hours. No display, no data network, no wlan, no gps, but about 1h of listening to music in this timespan.
I got signal inside buildings most time (with 0-2 bars) but it also happend to me that I was not reachable, even when I placed the phone next to an open window. Outside of the building I have maximum signal.
I did not have any problems with my older LG phone in the same situation.
Of course I know that this 42% are just compared to other battery users
@veyka:My phone is not placed in an isolated cage, and I want to be reachable in this time. Airplane mode is good for saving battery, but not when you want to use a "phone" ^^

Phone gives full signal so nothing wrong with the phones hardware or antenna .
Your alternative is to take the phone to a service centre .

Seeing as you're pretty much putting your phone in stasis for the 9 hours of usage. i think its pretty normal drain. it just looks like the only thing the phone is actually using is the antenna.
Just a wild idea, did you set the phone to GSM/WCDMA auto?

Yes, but does it matter, if I have no data connection enabled? If so, what should I use instead?
Maybe this battery "drain" of the cell standby is normal, when I do not use the phone in this time. On the other hand I am a bit confused, cause due Samsungs official data sheet, the phone should last up to 620h in standby with 3g enabled.
Of course the realistic value is less than 620h, but not 6 times less.
Ive come to realise that this might just be an erroneous stat. I honestly don't think it takes up 100% of my battery. Cell standby has actually deceased since I've flashed villainrom 2.1
any one else have a clue?
I had a theory that since my gsii its actually gt-i9100t not gt-i9100 it might make a little,difference.. whoo knows.. :/

mine lasts all day even with pretty heavy useage mate
you will get about 5 hours screen time on average from this device and battery .
I suggest checking to see if you have killed samsung bloatware that likes to run all the time , installed juice defender which helps a lot , adjusted your start up programs , installed latest firmware or a custom rom like leomar2.1 , if you cant get 3g signal switch to 2g only , switch wifi/gps/bluetooth off when not in use .
Doing all of the above will get you excellent battery life and you will easily last through the day .
The only way i can kill my battery in a day is with some severe gaming sessions and dlna sessions or internet browsing sessions
Battery and phone are fine its the setup thats important
Hope you get it sorted peeps and have a great day too
Look its really normal. You phone will use power in standby, so there is really nothing wrong. The numbers are relative.
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.

10-13 hrs is good by your usage..
If you've rooted your phone, you could reduce your clock speeds to reduce battery drain
May I ask why you have your data turned on most of the time?

I dont think that 10-13 hr is good by my usage ... My previous phone SE Arc was up to 17-20 hours with heavier usage.
I have data all the time turned on because i use Whatsapp and facebook messenger instead of SMS .
Even though the WhiteMagic and Novathor combo does give the impression of being more energy efficient, but at the same time, Sony guys could have thrown in a 1700-1800 mAh battery which would have been brilliant!! After all, of what practical benefit to the customers is making it more energy efficient left, if they cut down the capacity to level it up with the same backup as earlier with less efficient chip? !!

Hi I'm looking for a discussion rather than a Q so I chose this section.
I'm looking to chat with Go users about the battery life. How long does your battery last and what do you use it for? I notice that it
has a comparatively small battery but this doesn't always mean low battery - and I notice this phone IS being officially updated to Jelly Bean. I think the lower resolution screen helps keep the CPU and battery relaxed perhaps? What's your usage like?
Per Day Usage
Phone calls
Music
Internet browsing
I'm using the Sola and I hate the battery, I have to charge it 1-2 times per day. I use it for 1 hour of browsing, 1 hour of music, 5 minutes of calls, lighting texting - then it dies, I hate it. I'm considering the Go or J. The J has poor CPU/RAM but far bigger battery vs the Go.

The GO has a *****n nice battery life I'm using a Sola and get round 16hours. My friend got a GO and his battery was after 9 hours from 100 on 80%!!
After 9 hours, your friend's Go went from 100 to 80%? That's not bad at all! Does he/she leave the internet on? That seems to be a huge battery killer but I need it. If the Go could last 2 days I'd buy it now...
I bought my XGO two weeks ago, and below is my battery life and its usage (sorry no screenshots)
Battery Life:
100% to 15% lasted around 45-50 hours
2 to 3 hours screen on time
Usage:
Exchange push sync (email, calendar)
Gmail push sync (email, calendar, contact)
Outlook.com sync every 1 hour (email, calendar, contact)
No Social Network (Facebook, Twitter, etc) sync
light web browsing of 15 minutes daily
Power Saver implemented:
Installed BitDefender PowerTuneup (disable all network connectivity from 1 - 6am daily, except only connected to basic phone network)
Restricted all background 3G data except for Exchange, and Google native services
Location, GPS, Bluetooth turned off 99.5% of time.
Screen Auto 55%
Battery life is almost the same as my Galaxy Nexus, but my Galaxy Nexus can never get more than 2 hours screen on time even with 2000mAh battery, I guess maybe the screen used up too much power... Battery life for Go is pretty good in my opinion, would be super if it comes with 1600-1700 mAh battery...

Yes he did The whole day, his mobile Internet is activated and he has a screen on time of round 75%!!
I get about 4-5 hours nonstop browsing with brightness at about 30%, wifi and autosync on.
If wifi is off, I lose 2-3% while I sleep. That's about 7-8 hrs of sleep.
I keep data on and forced 3g during work. Signal is poor at my desk so with constant use I end up with about 30-40% after 7 hours if I didn't bring my charger.
Battery mileage really depends on how it's used and what's installed and what's running and how bright the screen is.
The bottom line is that this phone lasts one work day with me without having to charge.

My experience from Go's battery is that if you do not have 3G on is good. Otherwise it is draining too fast. I get 1-2 days battery life depending on the use. Usage is mainly phone calls and texting and a bit of browsing and checking fora through tapatalk or xda apps. For forum reading I use 2g/edge so to not drain my battery. Brightness is at auto with 100% max level. In general I don't think its battery cab endure a whole day of heavy use.. Screen usually drains 65-70% of battery according to statistics.

Xperia GO Battery Life
I got this phone two weeks ago after having a water ingress failure on my Motorola Defy.. what a shame, but now I'm happy. This ST27a is a great phone, I am not a phone movie watcher or gamer, so CPU and RAM are more than adequate for myself. Great look, light weight, perfect size AND waterproof (angels singing)... I ordered it unlocked and it came with ICS pre-loaded (4.0.4), at first it was such a huge disappointment as for the battery life, it was draining very very quickly almost needing two charges at day, there was a system update available but I was lazy enough to not install the Sony thing on my PC, then I finally got the weekend time and updated it (to the 6.1.1.B.1.10, KERNEL VERSION 3.0.8+) IT SOLVED MY BATTERY ISSUES!!!
The phone has a more than sufficient battery life, I do surf web every time during the day, have updates every 30 minutes for Gmail, Facebook, weather, news, everything, and it lasts from 8.00am at 100% to next 11.00am to 14% (which the preset low batt alarm sounds). Only thing I do is switch data off during night that's it. Screen brightness while in the office is at minimum but you can easily read it very clearly. I do take a lot of pictures for my work and some videos and still get that battery life. The phone is OK, just take care of which software version you have installed. I am sure that if I would turn the data off and activate it only while the screen is on, the batt would last at least two days (I will make this test and see what happens).... cheers.

With data, bluetooth and wifi off, I only lose about 1-2% overnight.
With Data on, this thing drains about 1% every 2 minute or so.
