Battery life and Charging time

I've owned the Samsung Focus S now for 12 days. I came from an android bionic. I have owned Windows Phones before, the Venue Pro and the Hd7. But this is my first Samsung.
For the first few days, the battery life was fine, a full day. But this past week I find my self hard pressed to reach a full work day. I don't play music during the day nor do I have many, if any calls. Mostly SMS and internet.
I've turned off as many background tasks as acceptable, limited the number of live tiles, set brightness to auto, and check email off of push. Yet this morning I reached 20% in about 8 hours.
In addition, I find the time to charge is extremely long. It might take 4-6 hours to fully charge from 80%.
Is this normal for a Samsung?? My other windows phones, and my bionic certainly do no present the same battery problems as this one does.
Thoughts, or is this usual?

Do you have wi-fi turned on? This is a real battery burner...
My Focus S usually goes through about a day and a half before I need to recharge. That's with a few phone calls, some messages, a bit of wi-fi browsing at night, etc. Email only gets checked every hour but it's on 3 different accounts.

while I'm home WiFi is on. Away from home its off. This is normal behavior for all my phones. All of them last at least 18-24 hrs, under the same condition.
Took it back to art. They said , lets try a different battery. I'm willing to try it for now.

I just wanted to add to this as I seem to be experiencing a similar issue.
I purchased my phone at the end of Dec, it's been great.
Now, since around a week ago I've been having issues. I used to get roughly 2 days use per charge and it used to charge quickly.
Now, the phone runs hot, the battery drains in 6 hours or less, and it takes many hours to recharge.
I turned off the one app running in the background. I turned off wi-fi. It doesn't seem to help. The battery itself doesn't seem to be too hot, but it's hard to judge.

I did a factory reset, and got a new battery. I then reinstalled less than half of my existing apps. In addition I've set my display brightness to medium.
Battery life has doubled, and the charging is much quicker.
Read an article yesterday about ads in free apps eating about 35% more battery. Who knows.

Even if they're running in the background? My Focus S takes a lot of time to charge and decharges so fast. 35% is no joke.

I'm also having some kind of battery issue, I have 2 batteries and they are both 100% charged but by the end of the day one is completely dead and the other is about 20%. I use my phone a lot for music and browsing over 4g and WiFi, but I charge by battery to 100% then go to the battery saver setting and at 100% it says time remaining about 5 hours. An when I turn on battery saver it says about 6 hours. On a full charge this seems crazy. Also with the homebrew battery monitor app. It says my phone is using over 4000mV. With screen set to low and in airplane mode. This is wierd.

4000mV? I assume you mean mA? not mV? 4000mV is only 4V which is about right, your voltage shouldn't change much, perhaps +-10% tops
if you do in fact mean Amps...
4000mA is 4A an hour, your battery would be dead in about 20 min at that rate and probably in fire as well
So, lets look at this in a different way,
2 batteries, that's about 3.3Ah max, you only had about 20% left in one which is approx 330mA so lets call it an even 3A of juice burned during your day.
An Average long day at work 12 hours
that's 250mAh current draw every single hour of that 12 hour day.
250 is quite high, but normal with the screen on and high brightness an wifi, however that isn't normal if you are normal and don't sit at your phone each hour for an hour for a whole day.
Things that can send your phone off on a amp burning spree? most common one is the backlight, set it to auto, and have a dark /black theme, AMOLED is the opposite to normal LCD screens where having a white background was best,
Next up is your signal strength, low 3G signal will eat your battery (4G is worse but thankfully we don't have that)
keep battery saving on all the time, it only kicks in when it needs to but I have seen dramatic differences having it turned off even with a full battery, im not sure what it changes when its not down to low battery but it does something.
background tasks can play a part but are minimal on WP.
I have 3 accounts on push sync, wifi and Bluetooth always on (but not always connected), I use it a lot during the day including several phone calls and web browsing, I start work at 8am, finish at 7 or 8 PM and im still sitting with 50% battery...
that works out at an average of just under 70mAh. that's about the normal level id expect, its double that if I turn battery saver off (even though it wont kick in until the last hour of the day)
oh I can make it go quicker when I show off the full capability's of our screens too

[Q] Is the battery life normal or faulty unit?

Hi,
Got the xperia z(c6602) for 10 days now, and am little worried about the battery life, yesterday got the firmware update to bulid no 10.1.A.1.434.
and wanted to clarify whether the battery is working properly or not, I got 17hrs 30 mins from the battery with 3g on and in which the phone was not touched for 6hrs,( though is not kept in stamina mode) . Total screen time is roughly 2hrs 30 mins.. attaching pics of the battery stats.. What should be the total display time to drain the battery from 100% to 0%, and how to determine whether this battery is faulty or not

I get 3:45 - 4 hours with 3g on and playing GTA vice city and RealRacing 3 and facebook and whatsapp all day long...I got to this stage by removing google+ which ******** kills the battery..look for apps that drains to much batt power..

I cant even get such figures in my dreams, playing games is simply out of question, as it drains battery rapidly and google+ is already inactive in my ph. i have attached the pics to show what apps i had been using, simply used ph for checking emails and whatsapp. and screen time is 2hrs 30 mins.. brightness at 20% does it imply i have a faulty battery.

Iam sorry but, I do not think this is bad battery life.
2 hours onscreen 13,5 in stand-by 6 \ 7 % phone calls and your battery is still green.
Not to mention it seems like your 3G is on and you do not use stamina mode.
Kind regards, Stefan.

Does that mean that i have a faulty unit?
Should i take it to the sony service centre, for replacement. ? Need help..

Well no, not at all.
I think the battery life of your Xperia Z is acceptable.
To give you something to compare with:
My Xperia Z is on battery for 12hours and 42 min now.
Battery left: 51%
2hours and 12 min of this are on screen time.
Only use my signals when needed and I do use stamina mode.
Iam pretty sure if you manage you signals properly and use stamina mode you get aprox the same results.
Yours and mine do not differ to much.
Iam pretty sure you could drain any smartphone its battery within 5 hours of onscreen time.
This the Z gives me aprox 4 depending on what I do, Id say its acceptable.
Kind regards, Stefan.

If you install some kind of backgroud task killer your Z gets better results. I got mine with Du battery saver and dx toolbox and got it runnig for 1d16h26m, and it stays it got battery for 3 more days (stamina mode on, all Google backgroud apps, FB apps and a few more are dead ).

I do not want to use a task killer, but freeze apps I do not use using Titanium backup.
3 days standby is easy when you do not much with the phone yes.
I achieved this aswell, just saying 12 hours in standby with 2 hour of onscreen use and 51% left is not bad imo.
Kind regards, Stefan.

But in my case 6 hrs of standby, with 3 hrs of screen time and total 18hrs plus (without stamina mode) is it suffiecient??

Install betterbatterystats from 100 to 10 and post screenshots of partial wake locks and alarms.

I had same problem man..and i was shocked with it.. İ got really disappointed with my battery but after reflashing stock rom with SEUS and full offline charging for like 5 hours am ok with it now but i am still waiting for more with 4.2.2 update!!!

Don't think 4.2.2 is a saviour for the Z. Once my Nexus 4 got 4.2.2, battery life went significantly downhill...

[Q] 4 hour battery life on heavy non gaming usage

i am getting 4 hours tops of batterylife on my z1
i have maximum brightness auto turned off i have wifi and bluetooth off
i have a live wallpaper
i have skype steam running in the back
it takes 2 hours for it to drop to 50 and 4 hours to 0 from full charge on pretty much full on screen time
is this normal even on that kind of heavy usage

I would recommend using wakelock detector to see what's really soaking up your battery. It's a free application and it's pretty self explanatory. Charge up your phone and use it heavily again and report back to us with your findings through wake lock detector.
Sent from my Nexus 7 using xda app-developers app

Have push mail on ? My phone was empty very quick before the update .257 but now its much better.
I think if you mean with 4 hours onscreen it is normal otherwise it is not.
Use wakelock detector already mentioned

4 hours on screen time with full brightness sounds reasonable. I can play heavy games for about 3,5 to 4 hours with medium display brightness.
Always keep in mind that the display is the biggest power consumer in modern Smartphones.

so the battery really is that bad?
using stamina it drops 20 or so % during the night

Actually the battery with its 3000 mAh is gigantic. And I think 4 Hours of heavy usage with full brightness is ok.
20% over night with STAMINA mode is too much though.

i have steam and skype whitlisted in stamina
really dissapointed in the battery life then
i guess theres no such thing as a full day of usage then
is there any smartphone that can handle that?

Do you actively use your phone all day (screen on all the time)?
With medium usage (WhatsApp, Surfing, Some calls) I can go for at least one, maybe two days.

I slept for 10 hours and my battery drained 9% with wifi and GSM on from full charge. your using the stock charger right? charging faster then recommended will reduce the life of the battery and can cause this kind of issue, but the phone is so new i wouldn't expect that to be the cause. I know the stock charger 1.5A. With a 2A charger it is likely the phone will charge at 2A.
Its probably a software related issue your having, but 20% overnight seems like a lot..

I would something is hitting your phone for wakelocks. 20% over night is a bit high. I know google currents is a know offender so uncheck that if you have it syncing. Try turning off google location access. Turn off gps and nfc. Using you phone at max brightness will always be very draining, leave on on auto unless your outside in daylight or in the car. Facebook is also bad for wakelocks. Any app that is polling for updates will be hard on battery. My experience has been a much improved battery life over my previous devices. On an average work day I leave at 8 and get home at 430, and I usually have 70-75 % by bedtime usually around 30%. I leave most my apps syncing all the time as well. I know the phone is new to you so I would say you might be playing with it more than you normally would.

I suspect that steam / skype will be preventing the phone from ever going to sleep.
I would suggest capping the max frequency of the cpu to quite slow or setting the governer to a conservative level (an app could be forcing the cpu to stay at a high frequency most of the time which will just drain the battery in no time)
However this usually requires a custom kernal or at least root which isn't very well developed on the Z1 yet.
If you can run a wakelock program that also logs the time spent at each cpu speed ... that would help people help you ...
As for any phone being able to handle it, unlikely the battery is relatively large but so is the screen, most phablets have only a fractionally bigger battery.
Only a full blown tablet will get you a much bigger battery that might be able to last you twice as long.
I typically go 3-4 days between charges on the .257 firmware without stamina mode and paired to a smartwatch 2.
I used to get 3 days on the 534 firmware with stamina mode! (i work in an area of very weak signal so i get 25% no signal time over a battery charge)

[Q] Xperia z battery draining

Hellow I'm a happy owner of the xperia z for 10 days, but I'm facing fast battery drain when using the phone. When Im just browsing the phone, battery goes down 1% percent every 3~4 minutes... When gaming battery drops 2-3 % every 5 minutes. I need some help, I didnt charge the phone the first time for 8 hours, but i read it is not necessary. I'm rooted, 4.3 jb, doom kernel v21. I have deleted some of the bloatware and i don't have WiFi and data on all the time. Also media server sometimes goes up to 21% in battery usage.

That battery drainage seems normal to me. Playing games needs alot of battery. Battery usage depends on several things, how high is the screen brightness etc.. To your media server: are you listening to music with your phone? Or watching videos? All this is done by media server.

Most times i close some, and.the phone is new.

1% every 3 minutes or so is not excessive drain. If you do the calculations, then that works out to 300 minutes to fully drain the battery, or 5 hours.
As the phone is new, it will take a few charge cycles for the battery to reach full capacity anyway, so see what the battery life is doing in a week or so.

As i know is not good to totally drain the battery. For example, i was talking to the phone and had wifi on right now, and my. Battery has gone down 14% in the last thirty minutes. My on screen time is at almost 2 hours, without gaming, and my. Battery level is at 43%
Edit i set screen brightness to 35%, my battery level is 41%. Sometines phone draws 1% every 2 and half minutes.

Yes, I know you shouldn't completely drain the battery. Total screen time calculations should be based on the full capacity though, or I could say I only get 1 hour screen on because I always recharge the battery at 80%! (I don't. It's an example).
Using the phone in different ways will drain the battery faster than others. The battery usage you described in your first post is not unusually high and will probably improve after a few charge cycles.

Battery life a bit odd? Amongst other things

Hi all, bit of background, I had my Z3c for just over 2 years and 6 months, heard the news about the XZ1c and soon as it was out I jumped at the chance of buying it.
Sadly, I haven't bonded too well with it.
Compared to my Z3c the battery life hasn't been all that good even using stamina. That's with minimal screen on time too. My Z3c used to do almost 2 days, this I can get a day and that's barely! Greenify is in use to kill apps etc.
After a full charge with battery care enabled I'm losing a load of charge and God knows where...!
SwiftKey absolutely sucks on this phone unless I have stamina turned off.
Vibration is bad, I've had to turn it off on the keyboard.
I also want to find a way to mod the stamina mode 3 so it's device performance but kills data too just as per the Z3C.
I'll attach some screen shots too so you can see what I mean... Just a bit disappointed.

Your experience is similar to mine. I have about 30% left when the day is over and that is with having about 2-3 hours of screen time. I turned off the majority of location and updates and keep screen brightness to a minimum. Despite not being as good as what I was expecting, it's better than the Pixel I had before this phone which couldn't make it through my usual 16 hour day without being plugged in.

that an estimated time only, depending on your history use.
but yeah z3c was kinda king with battery... i dont think this one will be. Sna835 is powerefficientier but remember that apps will be alway hungrier too.

It's better than majority of phones on the market... I think the Z3C spoilt us though, it was definitely king, even at its age it still gives well over 36 hours use.

Im having a great time with my xz1c.

My first charge
My first full charge is pretty good 51 hours alive with 5,5 hours screen on time.
I have disabled vibrations when typing, manual screen brightness (most of the time set at about 1/3), sync on all the time, Wi-Fi and LTE enabled all the time

Use gmaps, chrome, played 1:40h heavy game... Im satisfied with it..

The only strange thing I see is high battery drop over night.
It goes more than 10%, I was hoping for 3%. Phone idle battery consumption is on top then. I hope it will change in the future ROMs.
Do you guys see it also?

you can limit an app on background and also limit its data use. make a test: close all aps overnight and see if it changes.

I'm gonna try this, as I'm also seeing a big battery drop overnight. My Z3c used to drop 2% overnight, this drops massively.

I've noticed that Google Play Services seems to get the hump if you have any extended stamina mode. When I check app battery usage with stamina mode on, GPS is one of the top users. But not there with stamina mode off. If fact stamina mode seems to use more battery than if its turned off. I need to do a few more charges to confirm.
Battery life is excellent btw, better than any phone I have had before. Regularly getting to three days of use.

I have power mode activated with zx1 compact I disable the vibration jacket and some useless application kindeXXX is still improved battery life

So it's been a few days! So far I've:
- Changed my SwiftKey setting to vibration off,
- stamina mode changes to performance orientated instead of battery life biased like before,
- auto brightness off
- Limited MANY app's background data and background running as above (cheers for that mate)
- priority mode on to alert me of important calls only, everything else just uses the notification light with no sounds.
I'm now finally, because of the above, beginning to see 2 days battery life almost 3 days last week!
Still more to do for good battery like instead of just stamina mode On like on the Z3C but hey I guess I can live with it!

So as happy as I am... Still can't get to the bottom of why it loses the first 10% so fast?! Check this out, taken off charge like just over an hour ago and I've lost 4% already!
From 80% onwards it lasts a good while but damn man why's it losing the initial 10% or so that fast?!

This is my battery life for the last few days, it's been good... But this is doing my head in, losing first 10%so fast...

... And I've lost another 2% since that last post! Ffs man.

Can you tell me what is the Firmware of your device ?

Lost 15% of the battery while my 10hr sleep today. Very strange. My Z3c used to eat no more than 3% without any limitations, closing apps or stamina mode.
