I did a battery test on calls - Nexus 4 General

It's not very scientific, but I called another phone in the house, set them both on the table for about an hour.
After 57 minutes, the battery on my Nexus 4 went down from 53% to 47%. So if I try to extrapolate that, it's 57/.06 = 950 / 60 = 15.83 Hours of talk time. I did have wifi on at the time so I don't know if that helped the phone poll background data.
I'm just wondering why in anandtech got 8 hours in their test. Maybe the phone heats up a lot with a longer call.

That is much better than what I've seen. I lose over 10% per hour on a call.

I find the Nexus 4 (and most modern phones, really) to have good call life if it has the screen off / not on speakerphone. I can use it instead of my desk phone all day and still leave with 60-70% left at the end of the day after 1-3 hours worth of calls (plus the usual messing around on it, so an extra hour or so of screen on time).

How long does your battery last?

How long does it last?
How often do you use it?
Mine: 30hours or so using it once every 2 hours or so.
24-26 hours with no 3g wifi only 3 times a day for less than 5 min at a time to update weather no gps usage no bluetooth my backlight set to turn of after 10 sec and a total of less than an hour of phone calls per day. so i charge my phone alot
in general, i have no idea. but i do know i used my phone last ngiht watching youtube vids over wifi with no call, med screen brightness and it lasted about 4-5 hours. I don't think that's very good! lol
I lose about 10% listening to music for 45 minutes.
think I can get 24+ hours with maybe 20 minutes talk time over 3g maybe?/ not that graet anyways, whatever it is
I'm a heavy user. My brightness is all the way up. Screen stays on for 5 minutes. I turn wifi on at home to use the real internet. I talk for about 30-60 mins a day. I use 3G data when I'm not talking. I watch videos when Im not on the internet. I have a 2800mah battery. My phone requires charging after 8-12 hours of use. I just recently learned that half of my battery power resides in the last 5% on the battery meter.
It depends what you are doing. Seriously. WHen I first got it, I thought it was gonna die before the day ended.
On a typical day- 5-10minutes of phone, no 3g(i have edge,no 3g), 1 picture (just because I play around with the camera), pda about 10minutes, turning the unit off an on about once every hour or 2, internet maybe (5-10minutes), every 30minutes it checks email.
In 12+ hours I'm down to 85% battery. Not bad. I forgot to charge it once. By the time I charged it the following night (on for about 35+hrs) I still had about 40%.
It worked fine. But mind you stuff like 3g or always doing something that requires heavy power can and will drain the batteries.
With my constant usage, I only get around 5 hours max. I always carry 2 battery adapters with me.
dont know how long exact but i keep my screen at 100% brightness...3g is on but rarely use the connection...the occationaly wifi for updating weather and windows live email
i charge it everynight
I used to leave it on HSDPA to get mail every 10 mins, although make no phone call at all the battery only last a day and half. I was then disabled the HSDPA and 3G, just used GSM only, the battery extended at least to 4 days now, I still do get mail every 10 mins but only with GSM data. So if you find the battery do not last very long, you can try to do as what I did, disabled the high speed internet (HSDPA/3G) and leave it on GSM for a test in a day or 2. Hope this help everyone.
There are a few threads on this subject at the moment and I am sure the Moderators will thin them out but here is an observation I have found.
I travel quite a lot to different countries and use either my own SIM card or local ones to save money.
With different Networks and/or different operators, my battery consumtion changes radically.
I think it is a combination of Network polling (set by the local operator) and cell distribution (whether you phone is constantly searching for nearby towers) closer=quick fix father= constant polling that cause a problem.
This is over and above all our own device preferences and comms settings.

Test your battery life

I now understand that there are people who own the Diamond at the moment.
I hear a lot about the battery not being strong enough to last the day.
But then again, some say it does.
I would like for people to test this.
So post here the time you disconnected it from the charger (charged 100%)
What did you do with your phone during the day
- how many calls
- how long were the calls
- sms
- gps
- 3g
ect ect ect.
and what the battery status is when you check it again in the evening.
I think this is the best way to see how long it will last.
And if various users do this (one calls more, one internets more ect)
Then people can compare this with there own phone usage.
Thank you for your inputh
a dutch htc touch, i am still waiting for it. where did you get yours?
i am looking for performance with:
3g off (only connect when using the internet),
no pushmail (a lot of people that complain are using push mail)
no gps
no wireless
no bluetooth
does this mean i actually plan to use this as a phone???????
yes, with the extra of sometimes using internet and gps.
I my self dont have a diamond yet.
I first want to know how bad this battery realy is befor i do buy it.
Will it last 1 whole day, then its ok.
but if it doesnt last 1 whole days (and be able to use it! )
Then i will definitly wait for the Pro
HTC TOUCH DIAMOND BATTERY LIFE for an SMS junkie
UPDATE ON BATTERY REVIEW : I did this test, based on what a student (like me) would probably use. More sms than calls. Here's a rough estimate.
TOTAL HOURS BEFORE KONKING OUT TOTALLY = approximately 9 hours, give or take
TOTAL SMS-ES = 120
TOTAL TALK TIME = approximately 15-20 mins
TOTAL LIGHT GAMING TIME (Hexic) = 45 mins.
Its actually pretty impressive.
My verdict is that with backlight on "auto adjust" and with the dimlight dimming within seconds after not being used, there is a HUGE amount of power saving from running the VGA screen. Also, it could be possible that with its graphic accelerators, gaming also consumed less power than usual.

As another student, that sort of performance will do me!
So the battery only lasted for 9 hours on one full charge?
ok.. i charged my diamond yesterday night at 1030pm.
under locked modes and suspend...
no calls no msg no nothing.. i just left it sleeping there
now 330pm it's still alive at half cell.
Yesterday I used my Diamond for about 15 mins of calls, push email all day, connected to 3g half of the day, browsed the web for 20 minutes on HSDPA, browsed the web for 30 minutes on WiFi, played Teeter for 10 minutes (fantastic game).
By 7pm my battery was still at 50%. I'm happy with that. As a previous mentioned, the auto backlight feature seems to work very well.

different people will get different amount of time, for each person's usage is different.
SMS takes up a lot of power, because for the amount of sms i made, lets say 1 minute to type one sms, thats already more than an hour's worth of HTC Diamond's light being switched on. So it consumes battery
please do understand that your battery will be better after some cycles!!!
I'm busy throttling mine...
Streaming music via WiFi from my laptop, and I'm listening to it via Stereo Bluetooth Headphones.
Surfing the internet or installing and testing a few third party programs at the same time. I've made a couple of 10 minute phone calls, sent 17 e-mails (using push e-mail), and only two text messages.
I'm in a 2G-only area (my living room) with my phone set to "Auto" to supposedly keep searching for 3G. So far it's managed four hours, but I get a feeling it will be turning itself off in about half an hour.
Certainly seems to be getting pretty warm. Hopefully it won't blow up on me when I try and charge it...

thanks in Advance
i charged my diamond last night before i went to sleep. i even turned of the phone (flight mode). when i woke up (after 8 hours) the battery was down to aprox. 50 % and my diamond was switched on (screen was illuminated). so i think it must have been on for quite a while during the night which causes the battery to drain.
Thats annoying. It reminds me of my firts days with my tytan. The screen tunred on rendomly as well and drained the battery realy fast.
As stated above the battery seems to get better each time I charge it.
My first charge was hopeless only lasted half a day but each time I charge it, it gets better, its still not amazing battery life but for the size of it and what it does its not too bad.
Can someone post how many hours of music play you can get out of the Diamond?
Yesterday I unplugged my Diamond at 9am.
- it was constantly on Direct Push mail on a 3G/HSDPA network
- I've made around 40 minutes of calls
- I've used Google Maps with GPS active for 15 minutes
- I've transferred 2 albums (around 30 mp3) and listened to music for 20 minutes with speaker on (not headphones).
- I've shown my phone to friends (teeter, touchflo3D, ...) for half an hour
- I had my phone connected to my bluetooth car handsfree for half an hour
- I have surfed the net for about an hour
- Fortunately I didn't have to work yesterday, when I add up the time I've used my Diamond
When I went to bed at 11pm, so 14 hours later, there was 30% of the battery left. I think it's quite good!

That is quite good. I currently get that sort of performance out of my Touch (only roughly speaking, as it doesn't have all of those features). I think that, perhaps, the screen is the big battery drain and that people don't realise how much power they're using while typing texts, hence the differing opinions on the battery. Also, people haven't taken into account the light conditions that they've use the device in - the light sensor automatically adjusts the brightness of the backlight, as far as I'm aware.
time to charge the battery
slightly off topic:
how long does ist take for you to fully charge your battery?
i am just asking because mine takes about 5 hours to fully charge (phone turned on) and about 3.5 hours (phone turned completely off), with the supplied wallcharger. and this seems to be pretty long for an 900mAh battery.
thanks,

Xperia battery life?

Could someone explain to me why the xperia's battery life is so short. xperia has a big battery with a lot of juice, 1500 MaH is very high. for example the htc diamond has 900 mah but the life time is almost the same.
i ordered now a mugen battery 1800Mah hope this wil add some more life time.
sinds i am using wm6.5 the life time is now a little bit longer. is it the OS that uses that much battery or is it the hardware?
mine last for 2-3days
thats long for me i do exactly 1 day with it.
How do you use it like have you connection with the internet all the time. do you make a lot of calls?
mine usage is i recieve emails, i;m interneting for not more than 20 min. and make some calls not very special.
It depends on what you do. If you don't use it at all D) or use it for calling/texting it will last 2 or 3 days.
If you use it for media purposes (music, video, etc.), it will last 1 day or less.
Wi-Fi or GPS will drain it in 2 or 3 hours.
Background apps drain the battery as well.
Mine rarely lasts more than 6 to 8 hours or 12 if I'm lucky, when I'm outside/travelling/working.
If I'm at home I keep it plugged in the charger all the time, otherwise it drains in 2 hours due to heavy use lol .
Lol thats very fast orelsi. i use sometimes gps and have always connection with 3g. thats why i bought a reserve battery for my xperia.
mostly my battery lest for 12 hours or something and when i dont use it a lot the battery life is 1 day.
Mine lasts from the morning (7 o'clock) until the evening (12 o'clock). That is 17 hours. Then I charge it overnight. I am using (Hotmail) push mail all day, thus the HSDPA connection is always on. Another e-mail address syncs every 5 hours. Wheather forecasts sync every 4 hours. Newsfeed syncs once a day. I listen to music for at least 3 hours a day, sometimes up to 5 or even 6. Sometimes also internet radio through WiFi (drains more). When I'm listening to music, the screen is off. I get maybe 10 text messages a day, which make the phone vibrate for maybe 10 seconds each. I answer to those. I surf for maybe 15 or 20 minutes a day, checking stocks regularily. That's it.
Thats nice, if im wanna listen music it cant last till 12 o'clock. i also start mine morning from 7 o'clock. but it will ben nicer if it could last for 3 days with same use. sometimes i'm not home for 2 days and can't charge it (dont have teh charger with me) but then the next morning it almost empty.
so for me i have to take a reserve battery with me

Little advice for you, maybe it helps a little: Do not shut down your phone overnight, but turn the phone function off, that is to say disconnect from the network. This is what I do. With software like Spb Phone Suite you can automate this process, so that it turns off all connections at midnight for example, and back on at seven. I also use it for volume adjustment, it changes ring volume when I plug in my headphones. Phone without headphones needs to be at 100% to barely hear it, but with headphones, this blasts your ear I find... So the software turns ring volume down to 20% when I plug the headphones in
thnx i didnt think of that. i will use that

Very less battery drain, what did I do to make this change?

Last 3 weeks or so I have been optimizing to save battery power, read most of the thread but the best I could get was 12-16 hrs, surprisingly today last 12 hrs since I charged it fully, it has ONLY consumed 27% till now, daily usage include checking mails & making calls & xda forum browsing mostly.
I am concerned as to what made my battery so good suddenly as I want to follow the same foot steps, only thing i did differently is that I completely switched off phone (1st time ever while charging) for 2 hrs when the phone was charging.................could that be the reason for so good battery life?
After 24 hrs it shows 38% left (2hrs of extensive use in the morning with music in background), that is unbelievable to me, can someone help as to suddenly what is making this battery life so long?

Your past good karmas
im getting an avg backup of 2 days, with some music, camera and internet.
Maybe the telecomms station in your area just got upgraded?
I barely get through the day.
My usage is when my screen is on refresh all my mails. thats is
My internet use is hardly 1 hr and no music/game for the fear of my battery.
Today in 4 hrs i've lost out 15% battery.
What can i do here..please suggest.

Typical battery life so far?

Can people post their typical battery life times with the D3 so far, to get a feel for how good this is (hoping its a bit better than the JUST one day maybe) of most phones nowadays)

Well, lets see. I have set the radio to CDMA mode only, purchased the extended battery (+400mAH extra) and have GPS turned ON, Brightness at 70%, and Sync is ON.
Yesterday, I got to 70% after 14 hours of being on battery. This was with light use. 1/2 hour phone call, a few text messages, etc.
Today, I've been on battery for ~8 hours, and I'm at 80%.
A few days ago. I went a solid 8 hours of heavy use: using maps/navigator for about 20 minutes, texting, watched a part of an HD movie for 10 minutes. Had WIFI turned ON. Took some pictures, recorded video in 1080p, etc. My percentage was at 30% before I connected the battery charger.
Edit: My prediction: Once you have fun with the phone, set it up, get use to it, and then switch to using it for daily stuff.. texting, some calls, check your bank, watch a youtube video, etc... you can most likely get this phone to last more than a day on battery power. For me, as long as it gets me from wake-up in the morning to bed at night on just battery power, it's good.
I've got the extended battery, first day usage running it dead got about 38 hours. About 6-7 hours on the phone, some internet and a bit of texting. Suprising thing is, display is only using about 2-3% of the battery usage. Most is Cell Standby and Phone idle, both about 30% each.
Weird, I was getting horrible battery life with the standard battery, about 8 hours even with CDMA only. I put in the extended and maybe got 9.5 hours.
Today at home I have been using it moderately with GPS, WiFi, and mobile radio on and am at 70% at nearly 10 hours of use on the extended battery. Crazy, don't know what changed, maybe my signal at work really sucks...
14 hours 32 mins on my first full drain. That was with some decent usage. I'm probably going to pick up an extended battery though
Pictures say it all. This is with moderate to light usage. Some phone calls, text messages, browsing facebook, etc.
Display Brightness is AUTO and I have the extended battery installed.

Ditto. I was at a little over 30 hours today and at 40% when I plugged my D3 in. This is pretty normal for light days.
Hmmm something must be wrong with mine. My girlfriend's and mine have been getting around 11-14 hours on a charge. A "charge" would be when it gets down to at least 15-20%.
I don't have any widgets running really, except that stupid Verizon data app sometimes seems to keep trying to access something when I'm on wifi.
Not too good for me here. Down to 70% with barely any usage after about 4 hours. 36% of that use is cell standby, and 32% is phone idle. 16% system and the rest is apps and all are under 5%.
I barely even use the phone itself and haven't even made or received a call since getting the D3. Today so far I've sent 4-5 texts and checked email a couple of times so for it to be down to 70% is crap.
I'm giving serious thought to returning it and sticking with my OG for a while longer. It was running CM7 with stock kernel and lasted considerably longer with heavy use.
Took off charger at 720am and at 942 its at 80% no good, made two 2 min calls and had some txt and iys already draining, I don't have really anything syncing and im on cdma
Sent from my DROID3 using XDA App
Does everyone do the sync every X minutes or on push? I'm using push and that's probably what's draining the **** out of my battery.
For everyone having trouble with their battery: Have you changed your mobile network to "CDMA Only"?
If you haven't done such a thing, here is how to do it:
- At your home screen, Press you Menu Softkey and choose "Settings"
- Then choose "Wireless & Networks" at the top of the menu
- Select "Mobile Networks" at the bottom of that menu
- Choose "Network Mode" and select "CDMA Only"
If your settings were set to Global, then the system would be going between CDMA and GSM every time you signal was weak or it was trying to acquire a signal. By selecting CDMA only (Verizon's Home Network) Then you are telling your phone you are in the United States and to stop looking for other types of networks. This should greatly improve battery life, as it did for me.

Awesome, I'll try to remember to report back here my results.
I've done the CDMA only with HOME only selected.
6 hours and 40 mins since taking off charger, and down to 50%. About the same as yesterday.
38% of it cell standby,
34% phone idle,
18% android system,
6% display,
4% android os and
2% maps is the whole list of my usage since then.
It's a bit early to tell, but yesterday I decided maybe switching to CDMA only was meaningless while the SIM card was still installed. It's only been off the charger for a bit over an hour but I'm still at 100%. Typically it's been dropping about 10% an hour or so. Will update after a few more hours of use.
My battery life has been sucking. I am around 50 percent after a days use at work. With my Droid Inc 1 it was around 75 percent. I have it in cdma mode.
Cell Standby 39%
Wifi- 29%
Phone Idle- 26%
Display 4%
Android Os 2%
Android System 2%
Doesnt make sense. The Inc was rooted too running CM 7. Cant make that big of a difference.

After 6 hours I was only down to 70%. Typically I would be at 50 or even hitting 40 so there seems to be some improvement. I also noticed that despite having set it to CDMA only, after pulling the sim card, it was set back to global.
I have only had the D3 for a few days, and so far I can get a full day out of the battery. I listen to music via bluetooth FIPO all day (+9 hours) and I'm generally around 20% when I get home. However, recently the Social Location app has been going nuts. See attached...

So you've seen an improvement in battery life after taking out the sim card? Has your cell standby percentage decreased?
With my display on auto and moderate texting. Ill usually last from 10AM in the morning to like 11pm and still have like 30% left.
