this battery is way better... it works.. it is decent and it gets the job done. What has me quite out and *****in about is this --- i have like 3 wall chargers 9 usb cables car chargers from the whole horde of Dreams I have amassed (collectors item) and was looking forward to being able to charge the G2 up anywhere and everywhere. Now I am left with one little 2 foot long piece of strangly usb..that i have to drag around until i find a source of replacements. why did HTC not make the G2 with the same frigging female/male parts as the G1? its like ruthless capitalization of acessorization. *****es!
[G2 and Desire Z General] Superfrag:
All phones during the G1's time except for the iPhone used the mini USB style.

All phones this year and last year middle onwards have switched over the Micro USB that's found on the G2. No good phone this year has Mini USB, AFAIK, all Micro USB, obviously except for the iPhone.
[G2 and Desire Z General] under0ath888:
i got about 29 1/2 hours with normal usage on mine before i charged it and still had about 10% left.
[G2 and Desire Z General] Snuggl3s:
I'm going about 14-17 hours before I need a charge. Normal use for me, quite happy =)

[G2 and Desire Z General] Superfrag:
17 hours, down to 22%. Pretty impressive coming from the Vibrant.
[G2 and Desire Z General] dynamikd:
My battery has improved significantly once I let it die completely and charge til green while off. I did that twice and I'm loving the battery life now. The one thing I would recommend is putting the screen timeout to around 15 seconds. It helps significantly. I keep my twitter and facebook synchronized but I only fetch around every 3 to 4 hours. If I need it sooner than that, all I have to do is open the app.
[G2 and Desire Z General] mattseg:
18 hours, 30%... the vibrant couldn't really do 8 hours for me.
[G2 and Desire Z General] ezcape:
Are all these times/hours your getting for the G2. Is with the HSPA on? I havn't really timed my G2 just got it yesterday but its holding up pretty good so far. I was just thinking turning it to 2G speeds when you don't need H will almost double the battery life. Is there an app or option you can set when your phone is in sleep mode it switches to 2G and turn back on to H+?

[G2 and Desire Z General] Arcadia310:
I get 18 hours easily with heavy usage.

If I were to have the phone on airplane mode, silent, and no running applications it would probably last a week.
[G2 and Desire Z General] student.driver:
I've had a G1, a Nexus One, and a Charm, and this has great battery life. I keep playing Angry Birds and screwing around on it thatv would kill the Nexus One. I'm beginning to really like this phone. :)
[G2 and Desire Z General] ihateusernames:
I haven't really timed it but I kill it half way through the day. Then I charge it and kill it by the time I go to bed. I can't put the damn thing down.

I have noticed that it seems to charge rather quick. Or maybe its just the fact that I am actually getting things done when its charging and don't notice.

I am fine with the battery. I feel that once I get all the tinkering out of my system, I will have battery to spare by the end of the night.
[G2 and Desire Z General] mtl171:
Though there are enough iphones in this small world that you could almost claim that the apple connector port is standard. almost.
[G2 and Desire Z General] ThaGeNeCySt:
16+ hours... gmail sync with calendars, contacts, and emails... web browsing... Nexus Live Wallpaper, GTalk always on, lots of txting and phone calls.
[G2 and Desire Z General] ezcape:
Yeah I've noticed also my G2 charged fairly quick. I went from 20% to like 85% in an hour. Not sure if that's a good or bad thing? Hmm..

- Fly like a G2
[G2 and Desire Z General] mtl171:
probably a good thing. my ipod can charger from null to 80% in an hour. fast charging ftw.
[G2 and Desire Z General] Stryder5:
Hit 14.5 hours with some pretty decent usage.

Wifi on for 13 of those hours with sync enabled.

Brightness set to auto.

Good amount of texting.

A few calls through bluetooth.

A little web browsing.

Downloaded a few apps through Market.

A lot of gaming.

My G1 would never get this far with that usage without needing a charge. I'm sure I would've gotten better battery life if I had dimmed down the brightness but that's a good start :)
[G2 and Desire Z General] chewy106:
Can't find the CNET link at the moment, but all phone manufacturers (except Apple of course) agreed to standardize the charger by 2011, with micro-USB being the current accepted standard.

Mine was getting around 10h usage but after the first week is now getting ~24h to a charge with full charge. Daily over the weekend was a few phone calls, 100+ texts received/sent, web surfing, Yahoo! Fantasy Football, NFL Mobile, XDA, Angry Birds, random speed tests in new areas, USA Today/NYT reading, etc. At the office I turn it to Airplane because I have no signal in my cubicle, turning it off for lunch and 2-4 breaks a day (about 2 hours on, 6 hours airplane). Have 70% battery right now with 18h uptime since unplugged :) Battery is one of the few things I haven't had any issue with yet. And it can only get better after root
[G2 and Desire Z General] guruan01:
I was getting about 12-14 hours of heavy use (music, news, games, text, email, occasional photos, etc.)

Last night I unplugged my phone from the charger at around 12:30 am (fully charged). Signed out of facebook app right away to see if it makes any difference. Listened to music on my way to work (20 minutes). Moderately used my phone all day at the office. It's 4:45 pm now (16+ hrs), and the battery is at 72%. Pretty big change. Guess I'll sign off fb when I need to save battery.
[G2 and Desire Z General] SuperFly03:
OK.

I have a very nice observation.

Currently SIEDO doesn't offer an extended life battery for the G2. That's a lame duck situation for some of us. I used to have a 1750Mah battery for the HTC Incredible. When I compared the Incredible's battery to the G2's they were the exact same size and the exact same pin position but it didn't fit barely. The reason it didn't fit is because of one corner was slightly indented on the G2 which wasn't on the Incredible.

Tonight I took a dremel that one corner and BAM. The 1750 Mah battery fit perfectly. It is charging right now.

Incredible 1750Mah battery: http://www.seidioonline.com/product-p/basi17hhrv.htm

I will post photos tonight.

[G2 and Desire Z General] ThaGeNeCySt:
Should be... i think it just sands down whatever you put to it
[G2 and Desire Z General] SuperFly03:
I don't cut into the actual cell connections. You barely have to graze one corner to get it to fit. It took me about 7 seconds with a dremel to get it to work.

Photos are uploading now.
[G2 and Desire Z General] BW91961:
I haven't been able to gauge mine to well because I can't stay off of it. Also I got promoted and was moved to the middle of the building so now my network goes from H to E and even to G at times all day. That has to be straining on the battery wouldn't you think?
[G2 and Desire Z General] SuperFly03:
Ok, got the photos uploaded.

Phone plugged in with the extended battery charging:

Backside view (pay no attn to the fact that it says "This Side Down"):

Pictures of the corner that is modded. You can barley see it. All you do is place the battery in the phone and you will see what catches on the G2 case and trim it ever so slightly and the battery slides right in perfectly and is very secure.

Modded Battery (35% more life!):

Sorry the close ups couldn't be better focused. I have a point and shoot camera that just wouldn't quite focus right no matter what I did with the lighting in the room. It's no SLR :(
[G2 and Desire Z General] SuperFly03:
If you know you are limited to Edge then go into "Wireless and Networks" and select "Use 2G Only" it will save you battery while you are at work. Just a tidbit.

But yes, I agree, the change from H to E has to have some effect.
[G2 and Desire Z General] Orite:
I'm actually going nuts over my G2's battery life. A whole days usage at school and it's still kicking quite hard. Here's my distribution:

55% Left

12h 34m 37s unplugged

Cellphone Standby 31%

Android System 29%

Phone idle 25%

Display 8%

Voice calls 5%

Wi-fi 2%
[G2 and Desire Z General] ezcape:
How long have you guys had your G2s? Weird but not getting the same battery life as everyone else. I got it about 3 days ago. Did the draining and charging fully method. But I timed it left to work at 8am and got off at 5pm had 50% battery life. Which was only 8 hours. Almost to the point I was thinking about go to the store to replace my battery or the G2 itself.

I dont know about this, to me the phone battery sucks, im also using an iPhone 4 so maybe thats whats wreaking my time with my G2. I have to without fail charge it every night. if i dont ill wake up with like 10% or less batt life. my iphone depending on what im doing can go about 2 days. its been at day 3 since i got my G2 and have not been using data much.
[G2 and Desire Z General] ihateusernames:
That would be close to 16 hours if usage remained the same. Were you using it or was it just sitting in your pocket.

My G1 was on fumes after 8 hours.
[G2 and Desire Z General] SuperFly03:
iPhone has the advantage of a locked platform and extreme optimizations and no true multitasking.

Android does take a hit on battery life but since I've started using smartphones... I assume I have to charge them nightly (including the iPhone 3G I had).

Don't disagree the iPhone lasts longer on average... but there is a reason you switched to Android :p
[G2 and Desire Z General] llin:
Nice find! ~$40 from various online stores, worth the increased life.
[G2 and Desire Z General] vikramdhani:
Well if the battery will not blow in his face. i will surely try to give it a shot
[G2 and Desire Z General] SuperFly03:
Agreed.

Based on basic math the voltages are the exact same ergo I believe the battery will be just fine. I fully expect Siedo to release an official 1750 Mah for the G2 soon. However, if they don't you can mod a currently available battery to fit the G2 w/ little risk.

Mine is about done charging and about to unplug it.
[G2 and Desire Z General] ezcape:
I used it here and there. Texts, web, facebook, a youtube video or two. Or sometimes I take my phone out my pocket to just drag through the screens. When I really don't have anything to look at or do. Almost like a OCD type thing. Also it gets a little warm when it charges. Normal?

Let me look into it and hope it works
[G2 and Desire Z General] mattseg:
My battery life is insanely good. The vibrant would have been long since dead when I still have 50% left. I'm loving this device
[G2 and Desire Z General] SuperFly03:
So far so good.

I left it on my dresser overnight and the battery was still at 100% when I woke up 10 hours later. Granted I know it wasn't 100% exactly but 98-99% is more realistic.

Also, I found that I needed to turn off the phone after the light turned green (indicating full charge) and then the light turned orange (with the phone off) and continued to charge.

After a 20 min phone call with my GF, a few emails and texts the battery was at 90% 12 hours later. :)
[G2 and Desire Z General] Mactagonist:
Good mod! As long as you are only removing a bit of the plastic housing there is very little risk!
[G2 and Desire Z General] Snuggl3s:

Are you using a stock Incredible battery I can get from Verizon? Or a Seido?

- Fly like a G2
[G2 and Desire Z General] j.books:
cool. I don;t have any experience with hardware modding. do you have to have a dremel? or would a standard electric drill with an appropriate bit work just as well?

edit: I should note, my battery is pretty good as is. I use the music player on my phone and gtalk a lot, as well as the browser with some frequency. I unplugged it last night at 10:00 or so at not even full charge. it's 2:30 PM now and I'm at about 40%. granted, I was asleep for 7 of those hours. but still.
[G2 and Desire Z General] starfcker69:
My battery life isn't so great. I can barely make it through the entire day, and that's with minimal web, few calls and 2g only, and a tight handle on active apps.

I read on engadget that some believe that the second batch of phones has much better battery life due to a bug in the radio - always searching for signal (like roaming) thus churning the battery.

search for "second shipment"

http://www.engadget.com/2010/10/12/...to-add-wifi-calling-and-tether/#disqus_thread

This could be bs, probably is, but you never know.
[G2 and Desire Z General] j.books:
you shouldn't have that problem if you set the radio to 2g only. but yes, my phone did switch a lot from 3g to 2g for no reason, which I felt lie was using extra battery. even if I was in an area with plenty of 3g, it would swtich back and forth for no reason. so I set it to 3g only and problem solved. I understand however this might not work that well for people with spotty 3g coverage in their area. i'm in new york city and I always have 3g data reception.
[G2 and Desire Z General] SuperFly03:
Either one will work.

I personally modded my Siedo battery so I could put the stock battery back in the Incredible when I sell it.
[G2 and Desire Z General] SuperFly03:
I used a Dremel just because I had one with the appropriate tip.

you could really do it with a nail file or anything that can scratch soft plastic.

I've found my battery life to be hella awesome with the Siedo compared to the stock battery. I don't know if something was wrong with my stock battery and it was just being overly drained but with the Siedo it's fantastic. 14-15 hours in and still at 87% battery (mind you I was sleeping for 8-9 of those hours).
[G2 and Desire Z General] greensnow:
I've had many different phones and never trained a battery, would someone mind telling me the proper way to do it? I wanna try it out
[G2 and Desire Z General] innerlight:
I hope there's some trick to increase the battery life because something is nuking my battery. I think it may have something to do with the radio.
[G2 and Desire Z General] Snuggl3s:
What your supposed to do if I'm not mistaken is, drain your phone til it dies. Try turning it back on. Once it no longer does take the battery out then Hold the power button for 10 sec then place the battery back in. Try powering on. If it doesn't then charge the battery with the phone off. Ur supposed to leave it on charge for 2 hrs when the green light is on. So proly around 6 hrs or so. Do this 2 times one right after the other. Then u should be good. Hope this helps.

[G2 and Desire Z General] elracing21:
Well I just got a replacemtn on Sunday. That last phone was calibrated idk if I did it right but I wasted the battery first then charged and repeated 3 more times. It lasted me the whole day from 8am when my alarm goes off. I played music until 10:30 when my shift started. Only picked the phone up a few times to see the times and show it off to co workers. After that on the train ride home I played some games wile listening to music and by the time I got home to charge again I still has 50%+

With this replacement I did the conditioning a bit different. I charged the phone first then killed it and repeated 3x and it seems to be working almost 25% better. Guess I did it wrong the first time.

Today I woke up at 9am played music from 9:30am until 10:30am again pulled it out to play a quick game and to show off the phone to another co-worker then at 5:30pm I got off work and listened to music until about 6:50pm and have been texting on my phone since including this post without charging and I'm still on a whopping 54% holy COW!

I'm extremely satisfied with my battery life.
[G2 and Desire Z General] spovat:
For the past 4 days the battery would barely get me through my 12 hour day, with about 15% or less left. Today I turned off the auto sync and was at 50% when I got home. Its clear that auto sync was the biggest juice hog of them all for me. And this is with 3g on and pretty heavy usage (texts, app dls, browsing, fb). I expect it to last for about 16 to 20 hours on a full charge depending on usage
[G2 and Desire Z General] greensnow:
so is that the conventional way of training a battery? i havent even turned mine on yet I wanna make sure I do it right the first time haha
[G2 and Desire Z General] elracing21:
I can confirm it had worked better this way. If anything google it.
[G2 and Desire Z General] SuperFly03:

My battery life is good so far I make sure unneeded apps and widgets are killed and charge twice daily just to be above 80%
[G2 and Desire Z General] mgshute:
I have been streaming my slingbox for a few hours now, (starting with 40% out of the box) off the initial first then charged to "full" to run it down and have been keeping track of how fast its been dropping to see if there is much difference in a week or so.. I always have done this and my battery's just seems to have a longer total life span not really much of holding the charge longer. Lithium Ion battery's should not / do not have a so called "memory" so there is really no point to this. But I do it anyways. I do however NEVER run it to 0% as I know that's not a good thing for the lithium battery's from what I have read about them when the big switch from nickle went down..

Getting Crappy Battery Life

I don't know what I'm doing wrong, but yesterday I had to charge my phone twice to get through the day. I didn't get 4 hours on a charge and that was with pretty moderate use. Today, with pretty light usage, I got 9 hours. Any tips?
[G2 and Desire Z General] .A.J.:
I got 9.5 hours with heavy usage (many texts, some emails, at least 3-4 hours worth of calls (most on bluetooth), installed/updated about 20 apps, 1+ hour of web browsing, and messing around wit the GPS, live wallpapers and the like) yesterday. It was my first day with phone. Got it from UPS, fully charged it, turned it on and then barely put it down until it was at 1%. When I first turned it on I had it running with max screen brightness for over an hour straight before my attention was required by reality. Today I've been messing with it some but definitely much less than yesterday: Battery level is at 73 % and it's been on for 7 hours.

Only my second day with this phone but my G1 was a G1 (bad battery life in general) and this is how I treated it and treat the G2 starting last night:

I don't use a lot of widgets (3 or 4) and I limit widget update frequency (3 hours or more) when possible, I turn off whatever I'm not using (Bluetooth/GPS/wifi), I keep the screen brightness as low as possible, I usually leave the screen timeout at 2 minutes but manually shut off the screen when finished with it. Another thing i do is I leave it on while charging over night (it's my alarm clock) but turn the phone off once up and while getting ready. This usually gives the phone at least 30 minutes to top off the charge. When I turn it on I leave it on the charger while it boots up and then for a few minutes while it finishes syncing with email, widgets and the like.

I hope this helps.
[G2 and Desire Z General] greensnow:
im extremely impressed with the g2 battery life. I'm going on 32 hours and I've still got 15% with moderate usage.

I do believe that training the os (not the battery itself) to read battery status correctly is crucial. right out of the box i charged it all the way full, ran it all the way to 0% and did that twice so far. both charges I've had over 30hrs battery life (only charged it twice since i got it on tues)
[G2 and Desire Z General] Kubernetes:
The battery doesn't, but your phone does. Charging to full and discharging to empty "teaches" your OS where the 100% and 0% points are. If you don't calibrate right, your phone may cut off charging before you're at true 100%, meaning you get bad battery life.

Also, it may not be good for the battery, but I think a few discharge cycles won't do too much damage. And any damage will come in the form of shortened cycle life--not something I worry too much about.
[G2 and Desire Z General] Vulgrim:
was the charge to full with the phone on or off?
[G2 and Desire Z General] greensnow:
both charges were with phone on
[G2 and Desire Z General] pcgeek86:
Charge time

I'm coming from an iPhone 3GS, and I've noticed that the G2's charging times are excruciating. It only goes maybe 20% up in 2 hours -- has anyone else shared this experience? I'm charging off of USB, from my computer, not using the AC adapter.
[G2 and Desire Z General] elracing21:
Actually mine charges fast... in 2 hours from 0% to over 50% not exactly sure but I have never felt it was slow. Actually faster then any phone iv'e owned.

Try charging your phone and not using it. Turn off wifi wile charging.

Maybe your battery or device are defective.
