Battery life

I have charged it in the morning until it was full, and started playing with it.
It was on for 9 hours until the battery was completely dead.
I used it since 11:30 until 3:30pm, then I left it on standby for a 2 hours (battery was at 14%). I came back used it for another 2 hours, and it went dead.
Everything was on except for bluetooth and GPS.
Android Operating system used 83% of the battery and all the other application were under 5%.
I did quite a bit of browsing, photos, movies, youtube, downloaded some apps, etc...
What do you all think about the battery performance?
At the moment it is charging and I will leave it plugged in until the morning. It is also turned off.
What are your experiences? Opinions?

9 hours only? That's not good ... But probably you have quite some widgets that actively sync etc. etc.

i wouldnt worry to much as you probably just received it and you must have played with it for a while, and also try turning off the auto update of facebook, email etc etc

thats kindda dispointing, ... even with updating i expected it to last at least one full day, I mean when they put many widgets they should take into consideration the battery life ... hope its cuz the battery is new, and needs some few charges to feel maximum capability

As I said, I did have everything on apart from GPS and Bluetooth. (including updates).
And yes I did use it for 6 full hours (medium screen brightness).
Downloaded apps, watched videoclips, played some flash games, wrote e-mails, wrote texts, browsed the internet, etc... funnily enough I EVEN made 1 (one) phone call!
I wouldn't worry about it though. ALL my phones only lasted for about 8-10 hours the first day when I got them.

Doesn't new Lithium-ion battery needs a couple of charging cycles before
reaching optimal capacity!?

Would be nice if someone could update us in this thread about the battery life when you've had it a few days and it's being abused less

We must however point out a couple of things regarding the Desires out there at the moment, although we certainly do not wish to discredit anyone else's reviews.
We have been informed by a reliable source that some HTC Desires have been out for review for several days now, but these devices did not come from the same source as ours. These early versions did not contain the final ROM that we have been waiting for and I am reliably informed that those devices will have essential features missing. They have also had problems with the OS crashing and serious battery issues which is clearly down to the fact that Google had not completed the ROMS when the devices were shipped.

Could It be possible, that t-Mobile did not ship the Desire with the latest firmware?

I believe you are totally right.
I had my new HTC Desire from T-Mobile delivered today. It's a good phone but I have a problem. They sent a phone with pre-release software installed. Every screen has a watermark stating "HTC Confidential" and numbers.

Let's wait ~7th April and then we will see true battery life...

I'm fairly sure that 9 hours of constant use is pretty damn good for any device. If I use my Touch HD for browsing the net/listening to music/ syncing etc it will die in far less than that.
Remember that it is a miracle that the iPad lasts for 10 hours of constant use, and thats got a massive battery in it!
So yea get used to it! At least while you are playing with it being a new toy and all.

dont forget that the iPad has 9.7-inch (diagonal) LED display, so that shouldnt be a reason, and dont forget that the Desire's display is AMOLED which should be a battery life saver.
For the OP, if you could try using it the same (constantly) but disable the live wallpaper

Agree with the AMOLED, but it's running a 1ghz processor along with the already perceived power hungry android.... Gotta admit that if you expect it to last more than a few hours of playing with, will be sorely dissapointed.
Compared to my HD which had a 528mhz processor but lcd screen, which lasted less than 10 hours when playing with non stop.

It's not the same thing. "LED" is a backlit LCD-display, AMOLED is an active matrix OLED-display, completely different technologies.
TFT-LCD's use a backlight, OLED's has active pixels that light up per pixel and does not need an extra backlight.

The battery life is really poor.
I went to bed last night with it fully charged and this morning it was completely dead. Albeit I left meebo running in the background along with lookout and advanced task killer.
Nothing was set to update as I've deleted the friend stream and rss feed.
I'm pretty sure this phone should last a lot longer than 9 hours on standby.

If you have read the whole thread, you'll see that there might be an issue with the pre-released models. Unlocked/retail phones coming out next month with latest software will probably not have this issue.

I think someone should actually test turning everything off except gsm. No data connections, no updating of anything. No GPS, bluetooth, sync, no applications running. See how much it goes down overnight with everything off.

That could maybe be a good idea, just to see how much it goes down. But if you can't use the phone at all, I just can't see the point of having t his phone. It's made to be used and you are supposed to be connected at all times, so if HTC has made this phone with so bad battery performance, that just basically sucks.
On the other hand, it seems that the final ROM from HTC was just confirmed at Google this friday, so im guessing these early phones out there does not have the final ROM.

My Nokia E75, i run wifi all day, with push mail, and Zozoc (WiFi/GPRS Messaging client) and i can easily go through one whole day (and few hours). the screen is TFT, non-touch, and small.
I know that we cant compare cuz they are entirely different, but the point is, the battery life should not be (and i hope it is not) that bad, even when running apps in the background. one day (or few hours below that) should be decent.

The OS in the T-Mobile versions have already been approved by google, so its not a pre-release.
and i agree, someone should try to stop live wallpaper and updates (just use it as simple phone, calls, messages and a little bit of WiFi) and see how much that goes

I quote the following from the first detailed review from techradar
The battery in the HTC Desire was 'only' a 1400mAh effort - we'd have like to see a 1500mAh option there, as is the case with so many other smartphones at the moment.
We're also a little concerned about the battery life - it dropped rather quickly, and although you'll get a day's worth of use out of it under normal use (ie web browsing, calling etc) it can drop a little alarmingly fast at times.
We had a little look at what was munching on the power so much (thanks to the Android battery meter) and it seems to be the widgets (in particular FriendStream) and synchronising that's taking a lot of the power, along with the constant flicking to roaming networks and back to 3G.
We found a big increase in battery life if we stopped updating Peep, Friendstream and emails all day long, and when set to '2G networks only' the battery life also improved to three days' use without problem.

this seems good, this is decent! i dont use 3G much, i would probably update the friends stream on demand, and with a little bit above average use, i should get 1.5-2 days without problems (based on the review)
No I want some people who already have the desire to try this and come back with the result

Thinking about getting it

I currently have the galaxy s2. Hows the battery life on the nitro? Cause I had the LG thrill and it sucked and so did the camera. How is that on the nitro?
Sent from my SAMSUNG-SGH-I777 using XDA App

Stock, the battery life of the Nitro isn't so great. About in the neighborhood of 8hrs with medium usage. If you don't mind rooting, debloating and tweaking than you can get better results.
The 8mp camera on the Nitro is decent to good. Sharpness, saturation and white balance are about on par with any other higher-end phone. The negative though is it can take up to 6 seconds from 1st shot before you can take the next shot...So this is NOT an action capable camera.

I wouldn't say 6 seconds, dat's a little steep, but definitely not instantaneous; ballpark i say is somewhere around 3 seconds shutter lag, but that might be due to the crappy 16GB class 2 SD Card that comes with most of the P930.

No lag on Class 4 sdcard, rooted, hard reset and debloated.

what does that cut the shutter lag to? have you tried a faster card than class 4?

I have a class 4 and it takes 2-3 seconds between pictures.

sounds like the class 4 takes a little more than a second off the process. i'm getting ~4 seconds shutter refresh on indoor well-lit snaps, maybe a bit quicker outdoors in full sun.
anyone tried a class 10? usually overkill for a p&s but maybe with this device........

Processing lag is about 2 seconds with class 4 but then I havent seen a phone that was faster. Is class 10 on the market? I saw class 6 but the reviews said that they write speed gain was barely noticable.

Btw this is my second day without recharging mid day so the baterry is not near as bad as evo 4g or any mobile on wimax.
Also for anyone that caress, the touchscreen is a bit different than on sg2 or skyrocket (a bit different response wise). I definitely noticed that I am making less mistakes while typing. It seems way more precise than anything before.

It's probably related to finger-to-finger difference. My typing on Nitro is way worse then on Atrix 4g, with keyboard buttons smaller then on Nitro.

My typing on my galaxy s2 sucks lol
Sent from my SAMSUNG-SGH-I777 using XDA App

The keyboard on this phone actually drives me nuts sometimes. When posting for example, it's incredibly slow to register my inputs. But, over texting it's almost too sensitive. I don't know why but it also registers the first letter twice sometimes. I guess I just have to get more used to it. Wish it can be iPhone keyboard smooth.

just fine
At first I was skeptical of this phone.
Now, it works just well. I can stream music for an easy 6 hrs. I can do the same task I've done on any other phone with pretty much the same battery usage. If I'm having a slow day at work and I know I'm using my phone heavy I will plug it in and use it. Or if i'm driving I will have in charging. it's exactly the same way I treated my iphone or other phones in the past.
The soft keyboard is a bit touch and it does lag pretty good at times..
The phone is fair. There is really nothing out there that my provider can offer (BELL)
It's got the HTC RAIDER (even worse battery life) and the Nexus (no expandable storage) - which was actually the deal breaker. I do not like being restricted to 16gb max. I like to know I can carry another one with me or have a 32gb. I like to carry movies and music..
I still wish there were more phones with FM tuner built in.. That would be perfect!
Just my 2 cents I guess.

I bought the sgs2 skyrocket, exchanged it for the nitro HD, and then returned the device 2 days later. The battery life, even with little use, is bad. I would seriously think long and hard about making the switch.

It doesn't matter to me which phone folks get but 2 days with this phone is simply not enough time to accurately gauge this battery. Hell, I don't think a week is enough
This phone needs a fair bit of set-up, including full drains/charges and bloat cleared out, etc. but after more than a month with this phone I can say the battery is performing entirely different than it did on day 2 and it is not an issue (other than my trying to make it one).
The fact of the matter boils down to this for me:
I wanted the screen and I wanted the LTE. Those features are part of what defines this phone and those 2 features are the top battery drains and would be on any phone.

I agree with what Scott mentioned regarding the battery. A little over a month and now the battery can last much much longer even with gaming and all. Somehow the phone adapts to your usage and becomes more efficient. Not much more, but better than when it was fresh out the box.

I'm glad to hear that your experience is similar, says a lot about this device.
Another thing about the battery, it charges fast IMO. I like to let mine go to full drain before charging up and I just did a full charge in 1 hour ~40 minutes and that reflects most charge times for me.
I don't have much experience charging other smart phones but that's a very acceptable time for me.

Yup, indeed this phone's battery charges really fast, fastest of course with chargers that give out higher amps. Using the stock charger (1.2 amps) I can fully charge the phone at about the same time u mention, sometimes even faster. Using blackberry chargers (0.8 amps), it takes a bit longer, but still fast. It's nice to see a phone charge that fast. The atrix took a long time to fully charge, and that's not from a full drain too.

Something we keep forgetting Re: battery life

I've become obsessed with the poor battery life on my new Galaxy Nexus and I've been pouring over forums, videos and blogs to find out why it's so bad.
I keep hearing about people getting 8 hours, 11 hours, 14 hours before their phone dies, but this is not actual use time, it's idle time (I.e "I left the phone off the charger overnight and..."). WHY does the manufacturer rate this phone as having a 15 day standby life... FIFTEEN DAYS!!!!
Something is terribly wrong here. If I can't use the browser for more than an hour without the battery getting critical, then what's the point of a "super phone "? It seems useless. I don't even want to install games on this device, because I know I'll get frustrated by it chewing through the battery as I play.
I purchased this phone with a high priority on the HD video recording capabilities, but will I actually be able to film stuff while out and have enough juice in case I need to make a call? Something tells me I won't.
Maybe I'm just expecting too much or maybe manufacturers should stop making these phones so "super" and focus on the fact that these are portable devices which need to last at least the day. God forbid you went for a hike and had an emergency, only to find your phone dead after eight hours!
Rant over

My battery is currently at 60% after 13 hours and and 1:35 screen time.
I have absolutely no complaints about the battery. In fact I would say its the best out of any phone I've owned.

That's because when you pull your phone off the charger and it says it's @100%, it's lying. It's somewhere in between 95-99%. The first 10% is spent figuring out where you're really at.

I think op said it best himself. Maybe you're just expecting too much. Battery life is freaking awesome for a phone with a 4.65 inch oled screen. Reminds me of my trusty nokia e71 back in the day.

If your battery is properly calibrated, the first 5% is iffy. Just figured out how to properly calibrate less than two weeks ago and it doesn't include any software, like batterycalibration or resetting battery stats in cwm.

You can kindly replace "hike" with "family outing", "work", "movies", night club", "sporting event", "errands", etc... having a spare battery or charger (or a second communication device!) on you all the time should NOT be the solution to poor design (either hardware or software or both).
Sent from my Transformer TF101 using Tapatalk

Lot's of misinformation in this thread.
A new Lithium-Ion battery (LiCoO2) is always 100% fully charged at 4.20 V (+- 0.05 V). This maximum voltage lowers with age and use of the cell. Both voltage and battery age can be precisely measured by your phone and translated into the battery % display. It's not a linear graph but it's not really rocket science either.
There is no calibration of LiIon cells, it's neither necessary nor possible, they work at 100% efficiency right from the start.

i'm at 24% after 12.5h, 1:45h screen time (inverted theme browser and some brief facebook/twitter time...). This, to me is not acceptable. If I was using google maps + gps, how long until the battery died? 30 minutes? Less?? I'm not watching video, making calls, downloading torrents, using the camera or anything else that would cause this kind of drain, but it seems to be "normal" for a lot of users on this and other forums.

Have to agree with most and say battery life is by far the best compared to all other Android phones I've owned. As for standby time, this is tested without a sim card, apps, etc. So 15 days sounds reasonable without touching it and without the phone doing anything in the background.

I disagree.
The battery life of this phone is fantastic, more than what I expected. It is better than the Nexus S that I have.
I am using extended battery 2000mAh for GSM version.
Battery drain during night is about 1%-2% for about 8 hours. No kidding, I was surprised with that this morning. Probably because the new 4.0.2. Before, it was half percent an hour.
My current record for battery life was 61 hours with 4 hours screen on time. See the attached screenshot.
Again, this is based on my usage pattern.
Sent from my Galaxy Nexus using xda premium

Battery life is amazing to me too, My average usage a day at work is 8-9 hours music, 45-60mins 3g web browsing, ~1h 40 mins screen on time.
On my Desire HD (Yea I know, hopeless battery life) the battery would die around 7-8 hours in with that usage. On my Galaxy Nexus I get home with 50% left.
One thing I found that helped battery life out a TON, is swiping facebook off the recent apps menu when you're done with it. Also have a similar high drain problem with joystiq/engadget apps.
Running AKOP17 with francokernel12 for anyone wondering.

I think you need to specify CDMA or GSM. It seems pretty common for GSM to get around 4 hours screen time before the battery goes. CDMA: 2.5 hours or so with moderate-heavy use.
I really hope someone on Verizon will post that they get 4 hours screen on time (no wifi) and what they did to get it.

Battery is good here too. Android OS is the eater. 4.0.3 and a good kernel fixes that.
The phone is capable of good battery but the new OS is still buggy.
LTE EX Galaxy Nexus - AOSP KANG
Asus Transformer - 3.2.1 OC/UV

Franco Kernel with a core powered down on screen offm 325 / 1200 clock.
Exiting / logging off google talk
Entering camera and force closing it one time after each reboot
LTE off
Nets me 1% drain per hour on 3g with nothing going on. That is excellent battery life. Loging out of Gtalk netted me approximately 2% an hour and the camera close trick netted me a crap ton. Prior to that I was getting almost 8% per hour loss doing nothing.

[Q] Question about battery

Is it normal that my battery goes down a percent every 3-4 minutes, just by doing simple things like web browsing?

No. Something is wrong on your end. Check for any apps running the background that shouldn't be running at all.

Open the battery utility to see what is consuming the highest percentage of power.
The display is one of the biggest power consumers. What level is your brightness at? The new N7 can achieve almost 600 nits. That is ridiculously high. The ipad 3/4 and Mini max out around 400 nits. I've found 200 to be a good compromise between battery life and ease on the eyes.

I have. I even factory restored. The standby time is great but once I start using it the battery just drains like that

I would let the device die completely and charge it up to 100% and use it intensely for a bit and track it. My experience with Android is to let the first few cycles of battery settle in the kernel and all that. Sometimes Unix takes a few days to get acquainted with it's space in my experience.

I have about 5 hours on actual screen on time right now and I'm at 38% and 13h since I pulled it off the charger. Mine tends to drop a lot when using Facebook and playing games, cause they're memory hogs. I can listen to music and go on reddit for probably an entire day and it'll get 10 hours.

Most of the battery issues I've seen have all had the 5 hour screen on time problem, I don't know I just find that really weird but oh well

I'm also getting average of 5hrs screen on time. Nothing is draining the battery as far as I can tell. Today for instance I took it off the charger and went out. 7hrs later it had 96% with 6 minutes on screen time. It's at 13hrs on with 5 hrs on screen time mostly chrome, Twitter, instagram, Google+, quick games of words with friends and draw something 2 five minutes each game max if that. I would kill for anything close to 7hrs let alone 9hrs. Also the touch sensitivity goes bonkers often with my Nexus registering touches pretty far from where my finger is. I think I might just try and exchange it. Brightness at 20% maybe.

I have a battery drain issue with my new nexus 7. it cost 25%-30% battery overnight while i was sleeping. so i decided to factory reset it, and not installing any apps to test its standby time. it still cost ~20% battery overnight. Is it a defective product or it's a software issue? Maybe i should return it for a new one

Return it. There's no way you should be draining that quickly just in standby.

I almost have the same exact usage as you and have that touch screen problem too. I guess we don't have defective units

Battery Test
I pulled my new N7 off the charger thsi morning and decided to test the battery because it seemed to be draining too quickly for my taste. I streamed two movies, Star Trek (2009) from Google Play and The Apostle from Showtime Anytime. that is only 4 hours and 20 minutes of movies. My tablet died before the Apostle finished. Had about 20 minutes left on it.
I am not satisfied with this paltry battery life. Google website said it would run 9 hours of movies non stop. 4 hours isn't even close. There are several "comparisons" out there but they only compare what the company said. I am not sure the battery is all it is cracked up to be. I am going to do some further testing but right now it looks like I will forego the New Nexus 7 and pick up a Kindle Fire HD. That battery life does last for hours and for what I need it will suit me fine.
I welcome your comments.

Yeah the battery is terrible for some. There's a chance our nexus 7's are defective but maybe a software update will fix it? Who knows

I have same problems. Only about 5 hours screen on time, and it drains quick if I am streaming especially with Netflix.

What's the battery life like?

Spec-wise, this phone seems great, with the glaring exception of the battery's size.
I'm hoping someone with the phone could let me know, ideally as detailed as possible, what the battery life is like. Thanks!

Initial tests mentioned a screen on time of 4h+, which is nothing to write home about.
On another hand, even though we have a "mere" 3k mAh battery & 5.7" screen, the latter is amoled, which should offer considerable savings as compared to LCD.
I'm waiting for my unit to be shipped, will do some tests & share.

This is why it is somewhat tempting to go with the $399 5.5" model and the Snapdragon 625. You lose a bit from the 5.7" SD 820: no AMOLED, smaller sensor in the camera, only 4 GB of RAM, but based on battery tests with other phones with the 625, the life could be better than the 820 model.
Review units in the U.S. are starting to appear, TechnoBuffalo recently received their 5.7" and did a quick preview on it.

FYI. PCMagazine has a review up of the 5.7", SD 820 version. They managed about 7 1/4 hours on their video run-down test. The Axon 7 with the same test ran about 6 hours, Samsung S7 Edge, around 10(!).

They panned the phone though. TechnoBuffalo loved it, but PC Mag said the camera was shoddy and the UI is absurdly intrusive.

CNet liked the regular Zenfone 3 in a recent review. Though they too, thought the Zen UI was way too heavy. Seems to be a problem with some of the imported Android phones lately.
At this point I won't get a Deluxe unless it can be rooted, which I think is likely to happen based on Zenfone 3 progress.

It's the best thing you can atheistically look at. Battery life will get you one day of strong usage. Which combined with USB type-c that's nothing to be bothered by. I'd give the overall phone a solid 8.5 out of 10.

Battery life is terrible.
The same apps I use with no issues on other devices (including other sd820) cause a severe battery drain on the z3d.
My guess is the power management policy in the HAL, framework, or issues with the scheduler on the kernel level.
Initial investigation points to communication apps (Riot, Conversations), which cause a lot of wakelocks (then again, no such issues on other devices).
Once (& if) we have a bootloader unlock, this will be one of the first topics to address in custom kernel builds or custom rom builds.

I go ten hours at work with 2 plus screen time, 30-45 minutes on phone, 3 emails syncing, Facebook, instagram, Snapchat, two phone numbers, and I leave with 50% battery.

I'm in the same boat as mostly everyone else here. I'm heavily on my phone while at work as well (roughly 6 hours of constant use on most days with heavy internet usage as well). I stay at work 2 days in a row every 3 days, and in that time frame, I still go home with 30-40% battery still left on my phone.
If I were still using my note 4, I would have had to put the phone e on the charger twice a day for both of those days.
Plus, with the dual SIM feature, I don't have to carry around a work phone. My boss was more than happy to get me a nano SIM for my pho e when he found out both my work phone and personal phone would be one in the same and easier to contact.
So yeah, with the above stated, for me, the battery life is way better than what I have put up with on the note 4 for the past 2 years.

Battery is great for me. I don't have a SIM yet but use Google hangouts/Voice# and am constantly on my phone browsing and using different apps. I charged it 7 hours ago, it has 3 hours of screen on time so far, and battery is at 57%. It says it has 9 hours left (based on my current rate, I will probably hut around 7 hours of screen on time. That is on High Performance, though also without a mobile network connected. I am constantly connected to and using wifi though and location is on too.)
Plus with QC3, my phone charges from dead to full in an hour. It is crazy fast.
Edit: Correction, I am in Power Saving mode as I guess I clicked into it when prompted last time my battery drained and forgot to switch back. Didn't notice a performance difference though so maybe I'll stick with this mode until I play a game. Next time I recharge, I will put it in High Performance and record my Screen on time then.
