battery life

Hei all of you
It seems that the legend has been released to some people, and i was wondering what you guys get out of the battery.
I am currently on a Diamond 2, with 1100 Mha battery, and currently get 1½ day out of this, and i want this to be an improvement. The legend, with 1300Mha, OLED screen and newer cpu, sounds like it will be a lot better, but some review mentions the battery life to be really bad.
I am using my phone for 20 text messages, psuh mail, no phone calls and only visit a few websites on 3G. No bluetooth, wifi or GPS. What can i expect of this?

i'm sorry if my English is not good enough,
but i've the HTC legend since Friday, and Saturday i did a simple test, i put the mobile phone to charge Friday night, Saturday about 12:00 pm i disconnected the charger and i've turned the wi-fi, gps,and bluetolth off, only the 3G network was on.
I had also ebuddy running on the background, after 4 hours i didn't touched the phone, and my battery was about the 25%
And the full charge time was almost 2 hours.... i went back to the shop where i bought the phone, they changed my battery and the did a hard reset.
The battery performance is now a little bit better, but it has not the same performance as the iphone 3gs.

I think the first time you run your phone it will consume the most power. So it's not the right time to test. I suggest you fully charge and fully consume the battery 2-3 times and then put it for a test.

Full capacity of a battery shows up after 2 months.
You will pass from 1 day to 3 days

So here is one short statistic after second charging.
14% of energy left in the battery after:
39 hours since last charging
2 hours of display on (35% of energy)
37 hours of phone connected to the cell (36% of energy)
13 minutes of calls (13% of energy)
Phone used for me "as normal" - cca. 10 SMS, 2 hours of mp3 and FM radio, one hour of net surfing, running sync with Gmail and Google Calendar.

Yes, it is period of 1-3 months to get full capacity of the battery, but in first few usage, you can fully charge and discharge battery.
I have a one day of full usage of the phone (wifi always on, twitter, e-mails, calls etc.)

Getting better
It's getting slowly better with each charging, second week and I'm on two days. Everyone is using it in a different manner, but my battery improved for about a 70%.

got the legend now for 2 weeks and loving it.
Battery life is good, don't expect to go 2 days intensive use without recharge but no phone with these function have this.
I can easily go with one to two day with occasional wifi, gps use and keep 3g or sync on settled on 1 hour intervals while playing some games using apps etc
Blue tooth i haven;t tried but like any phone the power munchers are wifi, blue tooth gps and 3g.

wifi should save lots of power compared to network operator connection
i use wifi at office, and with extensive usage, i can get about 8 hours straight, that is pretty heavy, the screen barely got to sleep

I have tested the battery in plain sleep.
If the device has wifi off and mobile data off (and no sync, ofcourse) i guess it lasts for a week - 10 days. But then you cant use wifi or mobile data.
If you only let it be in stand-by (screen locked and off, no data or wifi or gps or bt) it last quite long, probably close to the stated 300-400 hours in the manual.
In real life that translates to 3-5% battery drain (tested by me for 24h, only sent 2 sms and talked on phone for 2 minutes) per day.
But in normal use, wifi will drain 5-10% battery per hour and 3g/gprs with autosync drains 2-5% per hour depending on net.
No device lasts for more then a day or two if you acctualy use the device.

I have had my Legend for a week and a half now and the battery life is also getting better with each passing day. I can easily use it for a day and a half with quite a lot of WiFi browsing, and up to 30 or 40 minutes of call time. I'm really loving this phone!

Hi fellow Legenders,
i've had the phone for 4 days now. i am having issues with my battery. I have noted some points that i'll share & hopefully find a resolution for my dismal batt life. I have bluettoh on all the time, but it shows very little drain based on BT alone. Other than that, this phone ROCKS!
After full 8hr charge, the phone lasted approx. 13hrs 38mins before reaching critical level with the following findings:
On 08 April 2010
1. Voice calls used 50% batt – 36mins 11s call time.
2. Display on approx. 30% brightness used 21% batt – on for 1hr 10mins 15s
3. Cell standby on 3G used 16% batt – on for 13hrs 38mins (no signal 1%)
4. Phone idle used 8% - on for 12hrs 28mins
5. Bluetooth used 5% - on for 13hrs 28mins
After normal charge till batt 100% (about 3hrs), the phone lasted 15hrs 12mins 41s before reaching critical level
On 9th April 2010
1. Cell standby on 2G used 50% - on for 15hrs 12mins 41s (no signal 3%)
2. Display on aprrox 30% brightness used 18% - on for 29mins 35s
3. Phone idle used 15% batt – on for 14hrs 43mins 5s
4. Voice calls used 10% batt – on for 4mins 14s
5. Bluetooth used 7% - on for 15hrs 12mins 41s
Looking forward to better batt life as the days go by.
cheers,
Su

Very poor battery life for me.It has 7-8 hours stand-by.
1.Every 5 mins e-mail control.
2.Weather with auto update.
3.Friend stream.
4.Background data and auto sync.
5.Enable always-on mobile data
6.3G
I don't understand whats going on.If i left device when i go sleep with full battery after 7-8 hours i look it.It shows me only left %35 battery.
After disable all auto-uptade and 3g its over 1 days.
My hd2 had 1230 mah battery and super big screen and 1ghz processor.It was using %10 with same usage.
Legend has 1300 mah battery and small screen and 600 mhz processor.It uses %65.
Can anyone explain this sucks status?

I m using the legend... and a hd2 as my other device. would say the battery life for the legend is really dismal...

I am happy to report that my phone batt life has improved tremendously since my last charge. I installed OS monitor & checked to see what might be hogging the batt, & discovered some program was keeping my CPU running inthe high 70's & above continuously. I killed that program, fully charged my phone till 100%, restarted the phone for good measure, & with BT on permanently, more than an hour of wifi usage, about half an hour of phone calls & about 30 smses, after 24hrs, i still had about 24% batt left.
So it has definitely improved by leaps. Hope that helps others who have similar problems.
cheers,
Su

it will be good if you can share what's causing the high cpu usage ...

Oh sorry i forgot. it was OpenWatch for BT watches. It has a problem currently with HTC Legend & SE MBW-150. It doesn't have the full functionality as yet for some reason. The reason it ran the CPU load up, was because i had turned off my watch by accident & set the program to search & connect to the watch. My folly really.
cheers,
Su

Nice battery time
I've bought and charged my phone last Thursday. GSM only, using WIFI every day for 15-20 minutes, 10-15 min talk, and it's still at 35-40% after 5 days. I've got a magic battery or what?

I can't believe this . I wanna just 24 hours stand-by.I hate to charge it everyday two times.

@ battery complainers

Not able to post a screenshot just yet, but here's the current status of my phone :
Battery on 21% currently
6 days, 4 hours, 0 minutes, 38 seconds on battery
Screen : 33% ( 3 hours, 28 minutes, 50 seconds )
Waiting time 26%
Phone is inactive : 26%
Voice calls : 4% ( 20 minutes, 40 seconds )
PES2011 : 3% ( 31 minutes, 30 seconds )
Android OS : 3%

So basically, 20 minutes of phonecalls, 30 minutes of gaming, 3 hours of turned on screen, and phone's battery is on 21% after 6 days of not charging.
The funny thing is - the battery section isn't displaying the web browsing/downloading I did on Opera in these 6 days ( had internet connection via wireless on my college ), the SMSing I did, and the 20 minutes I watched latest How I Met Your Mother episode.
( the only program I have installed that directly correlates to battery performance is advanced task killer; every time before I lock my phone after using it, I kill all processes running in background, including ATK itself; and of course, I manually disable bluetooth/wireless/data transfer after I'm done using them )
I haven't rooted my phone yet ( I haven't seen any JITs around so I don't particulary need the root yet ), so I can't snap a screen yet, but I'll try to get a friend to come over and take a picture of phone while on "Battery" section.
Hope this helps any future Arc customer.

This is pretty impressive
Did you use stock camera app?
2 days I used it and during the night baterry dropped from 24% to 2% overnight (at about 5-6h)
Today I charged it, used stock camera app. off/on Arc and then it dropped from 100% tu 94% or 95%, so definitely there is something with camera app.
My phone is also not rooted. I also lauch WiFi connection when I have to. It is off by default.
.184 soft.

screen on for only 3 hours just means you have left it in idle 24/7
I get around 2 days of moderate to heavy usage with around 150 MB 3G data every day

The camera app drain is one thing... I deleted some SE stuff which was still working in the background, so it reduced first draining way...I was happy few days, because battery life was cool, after 14 h of use it has about 40% left. Till today, the drainig came back and I dont know why:
I checked running process and there was something like that com.sonyericsson.usbdevice (dont know exactly but something with usb) I closed it and draining stopped...:-[
I suppose this process is related to charging and plugging to usb as the name suggest. Now I wonder if I can froze or delete this app?

My battery life has been increased after rooting and removing bloatware apps & moving all my apps to sd.
The only issue is with the camera, after using it my battery goes up to 40-50 mAh, while im normally on 4mAh. So, we all hope for a software update by SE to fix it..

My battery is awesome. With 3G on, BT on, my Arc lasts at least 2 days under moderate use.
However, it seems that someones really have the battery drain issue. I dont understand why and how to solve it. Just like my X10, I got serious battery issue while I read many posts showing how good their battery time were.

Battery Thread

Hi guys, can you post battery stats, including Screen On Time?
Thanks.

My first drain from 100% = ~22 hours of life with over 4 hours of SOT. Qualcomm Quick charge will have me back in 96 minutes. Pretty impressive for such a little phone.

Lasted a whole day about 20 hours until I reached 4% before I charged it again. Only
25 min of gaming
30 min video
45 min phone
3 hours use on internet
7 hours of calc player , Howard stern
Wi-Fi on all time
Display settings on default
No power saving mode
I'm impressed
The day after when I installed more apps it's more noticeable to see drain from certain apps that constantly use push notification like slickseals

First drain from 100%.
SOT around 3 hours
Automatic brightness
WiFi on 24/7, connected only when at home
Bluetooth on 24/7, also used with Android Wear
~5 hours of BT streaming (Play Music streaming over LTE)
7 Google accounts on Push
1 Outlook account on Push / 1 Verizon account on 2 hour Fetch (stock Email app)
Facebook / G+
Lots of apps installed...

Here is mine from today so far.
On pace for almost 6+ hours SOT.
I also have the Always on Display setting turned on.

The battery has been really good so far. When I checked the first time, it last for 16-17 hours total and 6-7 hours of sot. I was reading, watching videos, and playing games. I'm satisfied.

Pretty good so far I think. Far better than I ever got with the s6

Just under 7 hours screen on time from the very first charge.

i usually get between 4-4.5 hours screen on time and i use bluetooth all day with my headset along with streaming milk music with some games.

Yesterday/day before :29 hours with 5 hours Screen on time
Today: 20 hours with 6.5 hours screen on time
By far the best battery life i have ever had on any smart phone

I'm happy with this. Location always on high. Bluetooth on all day with my s2 classic.

Auto brightness and regular data the whole time, not bad at all

No complaints

So far battery is pretty good

I've been pleased. Wifi Calling and VoLTE on. Location services/history on (WiFi and network, GPS off unless using maps). Auto brightness. Stock settings, a few apps disabled.

How is yours blacked out like that?

Best SOT I ever got. Doze kept it alive at the end lol

Normal battery drain % per hour: what are you getting?

I've been on just browsing and I'm drained 15% in 50 mins is this normal?
Oh yeah... My screen is set to a very low setting so I don't understand why it's showing 93%
By very low I mean... One above the lowest so the screen's pretty dark

YouTube over wifi and lte, lots of browsing and most likely 200+ messages.

That's great! So how come I've only got 1:58:34 for screen time and 84% you've used over 3 hours and still your screen usage is 56% how come yours is lower?
I don't get it

AccuBattery Pro for me @ 90% this morning shows:
5%/h 265% in 53h 10m
Screen on 6h41m
Screen off 71h7m
Combined use 20h4m
I added Fandango and Regal Cinemas apps this morning (and used them each) and took a phone call along with some SMS, Facebook, Gmail, and Outlook use.

Here are screenshots showing my average usage times and drain avg per HR. (For some reason GSam Battery Monitor didn't calculate the app usage correctly )

The battery life of my Axon 7 is absolutely s*** compared to yours !
If I don't touch my phone for an entire day, it still goes from 100 to 0% in less than 24 hours.
4.7%/h
6h 9m active
Used 85% in 17h57min
Screen - 68% (3h15)
--> Discharge while on/off : 49/36
It would be really nice if you could put a screenshot of your "Power management for apps" (the app "Stitch & Share" can help ) and just say what you mainly switch on or not ?
Thanks !

I use my phone a little different from others. I have music or podcast playing for over 8 hours non stop when I'm working, as well as watch youtube on my breaks. I use bluetooth headphones so bluetooth & wifi are always on. GPS is always on high accuracy since I don't want to be bothered with GPS settings right before I start driving. I also get a lot of messages in a day since I'm in group chats. Since mobile reception at my work is very poor, if I leave mobile connection on, my phone will barely make it to 8.5 hour mark. However, if I turn on airplane mode (with wifi & bluetooth still on), the phone will still have around 40% left by the end of my shift. So I'm getting 7% per hour with the screen mostly off, mobile connection off, wifi & bluetooth on & connected

Here are my AccuBattery results which show which apps I generally use except I haven't used the camera at all the last few days.

Here are my Power Management settings, nothing turned on that isn't needed

Sorry it took me so long to get back to you, but hopefully I finally posted what you were looking for.

Mine is the A2017G model stuck at B02.
Just surfing XDA forms for 5 minutes drains my batter from 96 to 91 percent

Insane battery drain during activity tracking (Fossil Sport)

So, way back when I used my smart watch for activity tracking for 5 or so hours during longer bike rides and walks/hikes. This worked ok I guess and battery drain was high, but not insane. However recently I've tried using this again and now I can barely walk or bike for 2 hours and the watch dies. Battery degradation aside, this is insane. It drops about a percent per minute and when around 30% the fun starts where this even increases... Tried charging it at stops, but this increases battery drain even more (might be false reading of charged amount) yesterday we had a break at 1 hours 45 minutes, charged from 18 to 63%, but within 30 minutes it was game over.
Is there an issue with GPS? Because for the life of me I can't get the watch to get its own fix (not even using a watch app while not connected to the phone) and can only use the tethered phone. BT is than very high in the battery stats (70%ish) so is it still trying to get its own fix and using insane amounts of communication with the phone at the same time?
I tried other workouts, that don't use GPS but only step counter and/or HR and those can last for hours on end. This way this watch is no use anymore, who goes for activities only up to 2 hours?
