Battery life - how long?

Ok, so the Diamond has a poor battery life, but how poor? How many hours do you get out of yours without any ROM changes? How many hours do you get after tweaking and with ROM updates?
What about the newer extended life batteries? How much more life would they give? 20%? 50%? 100?
Thanks,
Jon

My battery lasts for about 4-5 days with normal phone and PPC usage.
(ROM 1.93 and no internet connection/3G/GPRS or GPS turned on).

Charge twice a day
I charge mine twice a day. I am a heavy user and have exchange server / push mail on all the time.
For this reason i have two batteries and change them every moning and afternoon.

If you rationalise it: Lets say with the 900maH you get 2 days, then what is your last question about. If you get the 1800maH battery then, then the life is dubbeld. Looks like a no brainer to me. Or do you expect us to guess at what your going to use, how long, what power it uses and then make a guess at the time?
Mine was tweaked and lasted more then a week, while on standby.
btw: Why not all your questions in 1 topic?

"doubled" looks like a no brainer to me, too... Apparently different people think in different ways.

Twice a day!!! Is that all! lol
I have mine on the charger at night; then if i'm on the computer the diamond is plugged in via the usb port; my half hour commute means she's plugged in the cars cigarette lighter, and it's plugged in a charger a lot at work. I'm a GPS, 3G surfing, mp3 playing bandit though.
If i aint doing any of the above, and use it just as a phone the battery will last a while. (at least 2 days) But if i just didnt want a phone...

With normal battery you can only watch two movies on Coreplayer and you're out. With GPS on you get 2-3 hours max. It's almost scandalous.
If you only use it as a phone, you get decent battery life, but I've bought it to also use it as a PDA. The battery is simply insufficient.
I've had to buy an emergency charger which lets you charge the battery on the road using any normal AA battery.

Does the HD7 have better battery life than the HD2 & Desire HD

Have heard various less than positive reports on the battery life of the two devices in the thread title & just wanted to hear from user experience, especially people swapping from the HD2 to the HD7, if it had better battery life?

I moved over from a HD2. I'd say the battery life is roughly the same if not slightly better on the HD7.

I would agree

I can't comment on the HD2 but one thing I would say is to not be put off by the initial HD7 battery performance. Mine has improved dramatically over the last few days.

i will say i was a lil worried at first as it was great for first 2 charges then it dropped really bad ie lost half the battery over night with no use, BUT, now it has sorted itself out the battery lasts really well. I get way more use than i did on my desire i mean way more like i would say 50% more. With all top end phones battery isnt going to be there strong point but i think wp7 is really good on this point esp as you don't have stupid apps running in the background draining it like on android.

Well that's what used to bug me about the Android devices that I have had, that the battery performance was less than great. This was especially noticeable on the X10 I had for a little while.

It depends on how you use it, my usage the battery doesn't survive the same sort of punishment my Desire does, my usage is mainly as a internet device on 3g, and compared to the Desire it really does drain the battery, as a mp3 player it'll probably piss all over the desire for battery usage, I'd take stock of how you use your phone and plan accordingly.

Like you I am a fairly heavy web user on any device I have so if this particular activity effects the battery life on the HD7 a lot then that's not so good!

Way better than the HD2, and unlike the HD2 it seems to be even drain the whole time, unlike the HD2 which seems to get to 10% left and within a few mins be at 0. I made a good 10-20 mins of phone calls on my HD7 when it said battery is critcally low and it didnt turn off even after the calls.

I had just gotten my HD7 2 days ago, but my battery sucks big time... Its almost like it is leaking badly that during a meeting, I was just messing with the marketplace and the windows live messenger, my battery dropped from about 50% to almost 0 (for the first charge). After second and third charge with lower average use, it still able to last me for a day (8.30am to 8.00pm). Lets hope its like what you guys said, need to stabilize the battery after a few charges. By the way, my HD2 is able to withstand almost 2-3 days in WM6.5, and about a day use for Android Desire HD OS (about 35% upon reaching 11pm from 8.30am).

My battery life sucks big time. If it is in standby it loses 5% battery per 2 hours for no reason, i already disabled the updates from microsoft and my email and calander syncs every hour. And when i'm on internet or marketplace my battery drops 50% in 1 hour. I have charged it know 4-5 times, I hope it will be better. I only charge the battery when it's on critical level.

Poor Battery Life
The battery drained very fast, less than a day with heavy used.
Another bad thing is, took more than 3 hours to fully charged.
No indicator to show the %, very difficult to monitor the usage.

You mentioned "5%" "50%" . . . .
How you get the % to show? or You just estimate.

I think Roaming has a big effect on Battery Life.
My battery has been fine, Awesome Battery life... Until I went to uni, I can get no T-Mobile signal in lecture halls so it roams to Orange, this seemed to kill my battery a lot halfway through the day the battery indicator was less than half full.

I switched roaming off. But I found something interesting, once again marketplace wouldn't open. (it always happens when I'm scrolling en clicking things very fast in the marketplace). So I had to restart my hd7. The battery was 10%, after the restart it was filled for 40% very strange.

How do you know you are connected to the internet?
Is there a way to see and stop the connection since that also takes lotof battery and ofcourse if you are on a limited plan that would call for a huge dent on the bills

So far, after 2 days, battery life has improved greatly since the first day. Much better than most smartphones I have used, and certainly way better than my current Evo even after using it for months. I suspect battery life will only get better as I break it in.
And yes, weak signals can cause significant battery drain regardless of what device you are using. The weaker the signal, the harder the phone tries to find or keep that signal.

Has anyone tested to see how badly the battery life is impacted by changing the brightness setting to high?
I was checking this phone out, and found that changing that setting really made a significant difference in the quality of the user experience... it didn't seem washed-out, like it does on the default setting. I'm just wondering how much of a beating the battery will take though.
Right now, I'm really leaning towards the Dell Venue... primarily because of the quality of the screen and the better battery. I don't care about the physical keyboard, so an HD7 might meet my needs if I can run it at full brightness.

Mugen powerbattery 1800mah for legend full review

Hei,
Ever since i saw this thread, I was considering a better battery for my legend.
To begin with the stock battery (Standard HTC battery) that came with the phone.
1. It used to last me for 2 hrs 10mins of voice call
2. If GPS was on it takes about 25mins to fully drain from about 95%
3. between 80to40% whenever screen was switched on, phone used to heat up.
4. At times (lately) even when the phone was in stand by in my pocket, it used to heat up so badly, i had to refrain from keeping the phone in my pocket. It actually felt like a "hotpack" in my pocket.
Phone is just perfect except for the retarded battery that comes with it. Whats the use an awesome phone if it you cant go through a day of light to moderate usage without requiring a charge?
So i decided to try out the mugen power batter. I love my legend, so even though battery was a bit pricey about INR.2,153.00 (USD46.95) (after shipping). I ordered a mugen battery 1800mah from their official website on 8th Nov. They took about 14 days to ship it to India from Hongkong (3 days waiting as batteries were out of stock).
Received it a week back. and currently i am running the 4th recharge cycle.
Immediately installed the battery on receiving it. (Couldn't wait!!)
The battery came with instructions to fully charge the battery (even after its fully charged as indicated by the green LED on phone) for 10-12 hrs for each cycle and nearly drain the battery before charging it again. (I took it to 5% each time, charged for a minimum of 11 hrs)
The fit
I was dead scared seeing the comments in this thread. But the battery was a perfect fit, infact the same fit as the stock battery. It would directly slide out without any poking / fingering
Tip - There is a small red plastic stick in the battery compartment to assist in battery removal. I dont have to use it though
The following are the actual statistics i have written down after each cycle. (Help me post a screen shot pls)
Recharge cycle 1
1st charge for 12hrs continuoesly
Voice calls 29% - 45min 44 sec
wifi 30% - 7 hrs 22min
Display 27% - 2hrs 12min (full brightness for 1hr)
Mpas 8% - GPS -23min, data 10mb
cell standby 4% - 7hrs 22min
phone idle - 2% - 5hrs 12mins
Total 7hrs 22mins from 100% to 6%.
Dint record the 2nd cycle, but was difficult to drain the battery in the next 13 hrs, had to switch on GPS + music on for 30mins on speakers + torch app with about 80% brightness for 1 hr to drain it before 11pm the next day.
I wanted to charge battery for atleast 10 hrs before leaving for office
Recharge cycle 3 Unbelievable!!!
3rd charge for 11hrs
Voice calls 12% - 1 hr 15min 12 sec
wifi + bluetooth 44% - 37 hrs 12min (dint turnoff bluetooth/wifi) transferred about 153mb in this cycle
Display 17% - 3hrs 12min (played angry birds for 1hr!!)
Mpas 13% - GPS -14 hrs 12min, data 43mb
cell standby 9% - 7hrs 22min
phone idle - 5% - 5hrs 12mins
Total 37hrs 31mins from 100% to 4%.
As you could see there was a drastic increase in battery performance after the 3rd recharge.
------------
Note - I am using juice defender (free version) + the phone is on strictly GSM only mode. (Exhausted my monthly data quota on 3g )
Currently I am charging it for the 4th time. Will post the final results again.
Also as froyo users are posting better battery performance, expect even more longevity of the battery once i receive my OTA (damn ever eluding update)
Conclusion - Definitely its a drastic improvement from the stock battery and the best part is it resolves the only problem i had with my legend, heating of the phone for no reason!
Makes me wonder why legend doesn't come with such a battery on default purchase.
Thanks Mugen for such a great battery
Do drop your comments and suggestions below or any standard benchmarking tools that i can use ...

Review part 2
< Reserving for 4th, 5th and final cycle >

Heating up is unusual with legend under normal usage, are you sure it has to do with the stock battery?
Some people did report problems with juice defender, your case may be different though.
Gotta say mugen battery was very lasting initially if you follow their instructions properly, but after using it for couple of months I don't think iam getting that same performance, its much less.. though still better than the stock one.
My mugen fits lil tighter than the stock one, its hard to get it out without that red lever. Iam kinda surprised about yours being the same fit as stock one. Dunno if they changed anything.

No heating issues at all after replacing the stock battery with the Mugen one. Havent changed / installed any new apps / software for the past 2 weeks. 1 week with the new battery.
So i can confidently say the stock battery is the culprit.

Hope mine gives the same performance at a later stage as well. Can it be that you got used to the longer battery life and dont realize it now?

I dont know if they have made any changes to the battery. My Mugen slides right out of the slot on tilting the phone after opening the case just like the stock battery!

It could be that, but iam sure it doesnt last as long as it was initially.. but still better than the stock one for sure.

Mine doesnt slide right out like the stock battery, it does need lil effort. (ie. the red lever) May be they made some changes after selling many pieces ?

I've experienced the same short life when charging through USB, but when I use the wall charger, it lasts much longer.

Going to bite the bullet & try out one of these, just awaiting the money to be put in my PayPal account.

great review..pavan
I would like the link to official page exactly where u did shop and also the detailed battery product number which we have to select...I am from Mumbai..

[Q] incredible S battery life

hey guys, hows your battery doing with heavy usage ?
and whats the idle power draw with screen off? because desire s has 20 mah... thats not exatcly right.. should be 6-7 mah tops imo.

Yup, power draw shows most on the display on mine too. Wonder why, but the battery life is kinda good though.

Had a couple of boring days at work, and managed to take at least 80% of the battery life in a 8 hour day with moderate to heavy use.
Not as good as the iphone 4 I had before, but better than the Desire, Galaxy S etc... decent but not mindblowing battery life.

Excuse me for my bad English
I think the battery is consumed by heavy programs or let's say programs consume battery like Live Wallpaper.
Live Wallpapers consume a lot of battery that many experts say don't use it if you don't want it.
I didn't buy the phone yet but I will after two weeks.

For more battery tips and programms running in the background also see topic:

Gladly reporting that the battery life on the IS is extremely satisfactory considering the display and other capabilities.
Got the phone a couple of days back, the first day i charged fully.
The usual setting up of the phone, bluetooth transfers, internet via 3g & wi-fi, gaming, and of course the regualr calls & sms.
The battery lasted me over 13 hours.. still had 14% when i decided to charge again.
now with the usage a little lesser that the excitement has gone down a tad bit, the battery is really efficient.
close to a day (maybe more) with above average usage.
btw, also noticed the battery usage does not seem to vary much with the usage of any task killers

My battery life so far has been pretty good, my old iphone used to die mid/late afternoon with the sort of usage I put my IS through yesterday (first charge)
Went to work around 8 am, checking emails and facebook every 30 minutes aswell as texting on and off all day. Watched movies and listened to music through lunch hour, downloaded apps. Continued the same as the morning through the afternoon.
Got home and was on it constantly (ebuddy, doubletwist, facebook, market) from 5 till around midnight when it finally died.
Very happy with it.

Question Average battery life

Hey,
Finally I bought this beautiful phone and used it for couple of days but I'm not verry impressed with the battery life
I only get 4:45 5 hours of screen on time
Is this normal?
What is your opinion about this?

There is a battery life thread already. Go there and read it. You'll find plenty of opinions.

SOT is a nonsense way to measure IMHO.
As it would really depend on how one uses the phone.
I get anything between 5- 8 hours SOT depending on what I do.
120htz, 5g, Bluetooth and screen brightness on 50%
Rest is all auto or adaptive.
Working days I come home with around 70% battery and them try to deplete it by playing COD and stuff in the evening and still have 40 -30 % left.
I do charge overnight regardless how much battery is left as I like a full battery in the mornings.
