So, I haven't seen this topic talked about yet, apart from manufacturer claims of the usual hundreds of hours of standby.
Having now had the TC for almost a week, I'm not at all happy with the battery life, and hoping it's either a faulty battery or something I'm not doing right.
Today, I've made a 2 or 3 short phone calls and downloaded a few emails, and it's down to 30% at 5pm! Most other days have been the same.
I do have bluetooth and HSDPA on, but not Wi-Fi. Surely, this won't be another case of, "buy this great phone with all the fast connections, but stick to 2G GSM because of the battery life".
Any help gratefully received, as I love the TC apart from this problem.
Data connections come from the "TalkTime" budget, not the "Standby" budget, so if you leave your HDSPA connection connected, or your Bluetooth on, it will drain the battery in about 7 hours.
My tests seem to indicate that HTC's estimates are reasonable within about 85%, if you understand what they're saying. If you leave your phone switched off, doing absolutely nothing in the background ("Standby"), then I've got about 200 hours out if it. But as soon as you start using the phone (which includes switching it on - the increased processor usage and backlight take more power than Standby) the overall battery budget is reduced.
An example - if you spend 1 hour online, you've used 1/7th of your TalkTime budget, but you've also used 1/7th of your Standby budget - the hour of talktime is equivalent to about 30 hours of standby...
It's marketing speak, sadly, but given USB recharging, etc., as long as the phone makes it to a laptop or socket each evening, I'm pretty happy with the battery life on my Touch Cruise - just remember to disconnect data connections when you're not using them, don't check for new mail every 5 minutes and only use IMAP IDLE when you really need it...
I too was first disappointed but I had almost everything that uses data switched on or on automatic like weather and emails.
So I set everything to manual and batt is good with some calls. Before when I tapped on the top bar there was always something connecting or showing connected for a x number of mins. But now it shows 'No data session active' and batt is holding up nicely for all my calls + what I need like GPS etc.
I do put TC on heavy use and I am quite satisfied with the fact that TC makes it through the day.. Most of the PDAs and phones I have used forced me to carry secondary battery with me..
I can only go on my heavy day to day business use with push mail 24h, 20+ calls, few hours of TomTom and bit of forum reading!! But it´s a very big improvement on my Kaiser which would be empty by 7pm. Whereas the Polaris is still around 50-45%
Can anyone tell me how much battery life can one expect for mp3 playback?

Something's either wrong with my hardware, battery, or config.
Are you in a 3G HSPDA area? I am, and wondering whether or not that's killing the battery.
If it's the battery, I doubt I'll get an exchange, seeing as most places are sold out of TC's still.
Do you use Windows Live? I don't have MSN Messenger running, but I think it syncs all folders on my hotmail every 2 hours.
I don't use Windows Live or the messenger. I'm now using HTC Mail which gives you a free 3 months trial of their Microsoft Exchange Server account. It works really well and seems to use less battery than the Windows Live, which I had previously used.... and most of the time I use the basic "G" (GPRS) connection although when surfing the net I change the connection to 3G.
Hmmm
Thats interesting
Im having a similar problem.
So far, mainly used mine for browsing through wi-fi but the battery drains so quickly. It only lasts a day and a half.
Same usage on my old orbit would last close to a week.
ps - Ive swicthed off all other comm functions
I'd be delighted with a full day! It's such a pain to have to keep plugging it in!
I've now switched off HSPDA, and if that doesn't work, I'll have to switch off 3G. Kind of defeats the object of having a 3G device.

3G/HSPDA uses a lot more power than regular GSM. I keep my phone locked to GSM and only enable 3G when I want to go online, but then I primarily use my phone as a PDA so I don't access the network that often, even for voice.
I think there's a utility floating around these boards called something like BandSwitcher that does something to make it easier to toggle between 3G and GSM. As you can probably tell from my vague description (and I'm not even sure that I got the name right), I haven't got round to investigating this fully myself yet.
By the way, there is another thread here about battery life, started by me (what is it with us Brits and our obsession with battery life?), and called "Dissapointing battery life test" (http://forum.xda-developers.com/showthread.php?t=356910&highlight=Julian+battery+life). The thread includes a link to a very useful tool written by Muyz and available here (http://www.vandenmuyzenberg.nl/PowerGuard/) that allows you to look at current drain on the device and I posted some data in that thread from my device so you could run the same tests and see if your current draw is comparable to mine. If you do this then please do post your data.

I'm afraid that's a very unhelpful "it depends". It really depends on (a) exactly how you've encoded your MP3 files (bit rate and CBR vs VBR) plus what player you are using to play them.
Having said the above though, I can give you two data points:
1) The Touch Cruise manual claims "Up to 8 hours (WMV). Up to 12 hours (WMA)." (This is on page 249 of the English manual under the power/battery specification.)
2) From measuring current consumption on my device while playing 64kbs AAC HE files I estimate that I'll get somewhere between 9 and 10 hours before I go from 100% charge down to the 10% warning level.
AAC HE is very CPU-intensive to decode. I'm not sure how WMA compares to MP3 regarding CPU intensity but I would expect your figures to be more comparable with the WMA figure quoted by HTC and, in light of my AAC HE real life experience, the HTC figure actually seems quite realistic (although nowhere near good enough in my opinion).
I hope that helps somewhat.

That's fantastic, my battery MUST be faulty! Oh, and thanks very much for taking the time to write all that down!
I'll leave it another week or so playing with turning things on and off, and if I can't get a full day, I'll order another battery, and be hardcore about the 16 hour charge for the first three charges.
When it comes to my batteries I am a stickler when it comes to conditioning them. I always do a full discharge and recharge for at least 3 cycles. It may be inconvenient the first few times because you can run out of power in the middle of the day when you really can’t wait for a recharge, but in the long run its worth it. On the weekend when I use my TC the least I get 2 full days out of it.

Looks like it's paid off!
I've had my second day now where it's lasted a day! Last night it had 40% on it at 0100, and so far at 1700 it's still on 70%. The reason? I turned off HSDPA on Sat, and it really seems to have made the difference. The internet still runs very fast as well.

Hi
Where did you get this info from? I've heard of ppl doing so for NiCd days, but never heard of doing it to LiOn or LiPoly batteries.
Hi all
someone knows, if powering OFF the TC suspends the WIFI-connection
so that it will not discharge the battery?
On my elder HP, I let the WIFI on, switch off the device,
and I couldn't remark a greater change in the battery after one nighgt.
On TC, when switching OFF the unit with WIFI ON,
the battery is empty after one night.
Tanks
St
I just got my P920 3 days ago. And tested different firmware, King 3D, Kingdroid, Official FW.
But it all have same problem, is the wifi speed is only 65mbps.
(Router: Asus N-16, my notebooks always connected at 300mbps)
Is it the P920 wifi-n max speed just higher than wifi-g a little bit? Or the firmware can still be improve?
Could anyone share the wifi connection speed?
Thankyou~
I too have the same problem but have chosen to ignore it as my laptop seems to rarely hit 130Mbit either and when it does I haven't noticed any improvement in real-world speed.
At the end of the day I can get sustained transfer at 3.6MiB/s copying files between my P920 and the PC over FTP. That seems pretty reasonable to me.
You have to consider that 802.11g at 54MBit is about 1/3 the real-world speed of 802.11n at 65Mbit. Yes that might seem odd, but its to do with the changes in how the protocol works.
Also bear in mind my laptop has two antennas but the P920 only has one. So while it might technically be 130Mbit capable, it could be that you need a really REALLY good signal for it to work. I suspect there are just far too many WiFi access points in my area for it to reach full speed.
I usually copy movie to my p920 to watch in bus/trains. It take me very long time as these files are almost 2gb. Actually I want to use a USB cable to copy files and charge the phone. But this phone charge using computer USB will take longer 3 times than the original charger.
(My previous Android phone(Acer) just longer 30 minutes than the charger. I don't know why p920 take 6-7 hours to charge using computer usb )
If there have a way to charge faster using usb, that problem can be solve.
Sorry for my poor english
I take it back, I tested my laptop with a different router and I can hit 7.4MiB/s easily (showing 130Mbit) and its even getting 4.2MiB/s from my normal router (showing 74Mbit) today (it tends to be low because one of the antennas is swapped for an external yagi so impairs the MIMO ability).
My Optimus 3D is still refusing to go above 65Mbit however no matter how close to the router I get. Lets hope this is a bug that gets fixed as I'm almost certain it should be able to match the performance of my laptop.
I agree the Optimus 3D does seem to charge slowly over USB, but then USB can only provide 500mA and the charger as I recall is 1200mA. So it makes perfect sense that it will be 2-3 times slower.
I also noticed that if you put the screen on top brightness while running a CPU/GPU intensive app you can actually still drain the battery even while plugged into the charger. I suspect that may be the charging circuit switching off due to the DC to DC circuit heating up under such heavy strain. Its not a flaw, just something to consider.
If I set the router (HUAWEI HG655b) to just 802.11N, my O3D won't even connect. It says Connecting... Disconnected. What can I do about this?
anyway i can increase the samsung galaxy tab plus 7 to perhaps 8hrs to maybe 10 or 11? i see my ram is using more than half and i dont feel like waiting around for a rom to be developed because i cant find any out there yet!
If you are on the older KL1 firmware you can give Garyd kernel a try since you can under volt the tablet to conserve battery.
underclock
You can try underclocking. There are several apps in the market (you have to be root). Also, check if there are consuming too much processor time. For example: I've found that Dolphin uses more processor than the stock application (you can hold your finger on the home icon to quickly check the apps running and their use of memory and processor).
7~8 hours? Lol. Dude, don't expect too much. Samsung didn't change much from Galaxy Tab 7.0.
I was using N-mode Wifi, 3 tabs browsing internet 2 hours, and remain battery was 49%. It may not start at 100%, but I am sure it started at least 95% battery. C'mon, Samsung. I just did 2 hours internet with 3 tabs, and remain was 49%???
I was a user of GT 7.0 as well. It gave me at least 6~7 hours. But, GTP not.
I dunno about that. I'm taking a break from studying and noticed I'm only at 40%. Ive been Switching between pdf's and four tabs in the stock browser (which is in desktop viewing mode too) off and on throughout out the day.
Ive had this thing unplugged for 13 hours so far today, but have been aggressively using it for about four hours total. For as small as this thing is I think it does a damn good job.

Same here. I don't live on my pad but I use it for note taking at work, skittles research, and some recreation and it gets me through work at les than half used. No complaints.
really bad battery life
I have a wifi version p6210. I only get 5.5 hour max. usually 5 hours. No problem with standby, drains little battery.
I use my GT7+ for browsing most of the time - mostly forums such as xda, read news watch short flash news clips. Nothing intensive, no desktop widgets. I use Dolphin HD browser. I have garyd9's CWM + root (NOT his kernel). I have CPU Master and it says the cpu runs in ondemand mode.
I tried the auto screen brightness, calibrate battery stat etc. they make no difference. I also ran youtube video in the browser continuously and it still drains the battery in about 5 hours, same as less intensive browsing.
My original 7 inch GT can easily make 7.5 hour.
I used PropModder (also tried with Blade Buddy) to change the wifi scan interval. It's set to something ridiculous like 30 seconds, but to complete a full scan especially if there's a lot of APs in the area takes 20. So it ends up always scanning. Mine's set to 150 seconds now.
Make sure you turn of GPS when you don't need it, and turn down screen brightness. I just did a long haul standby test and (with wifi off) got almost 13 days of standby time. 100% to 10%
I get exceptional battery life out of my wifi tab. I turn auto-brightness off and adjust that manually, turn auto-rotate off when I am reading, turn wifi off when not near a network and this thing doesn't ever need to charge during the day.
First of all, for the most part, after about a month of owning the one x, these haven't been much of an issue for me. With that being said, I want to keep it that way so I am wondering how people are handling a couple of things:
First, because of the good battery life, when I go to bed, my battery is usually sitting around 40-50% left. That puts me in a bit of a dilema because if I don't stick it on charge, I will be hurting the next day. I'm also hesitant on putting it on charge because I've always heard that you should let the battery drain a bit more than that and that charging it at that level over and over isn't good. So, what do I do? Before, I'd just not charge it and swap batteries with a fully charged one and then rinse/repeat.
Second, with 10GB of space available, I'm sitting at around 5 GB free. The two main things I have that are eating up some space are nandroid backups (at 1 GB a pop) and my titanium backups (around 500MB). Add to those my couple of ROMS (around 300-500MB each), some themes & other misc mods, not to mention a handful of videos... well, things are beginning to add up quickly. I'm trying to come up with some sort of automatic/hand-off/set it and forgetit type of setup to handle this. I'm starting to try out a product called folder sync to move files up to dropbox at some scheduled time. I'm just struggling with how best to set things up. For example, a really need the last nan backup sitting locally. I also think my titanium backups (set to only 1 in history btw) would be best sitting locally. My current rom .zip (I dunno), if I need to reflash, then locally would make sense. Some videos could go up to dropbox, some that I use more frequent should be local cause I don't want to get that dreaded throttling on my unlimited (cough cough) data plan. I do own tasker (although I'm no expert and mainly use it for syncing accounts). Foldersync has scheduling (and also a tasker plugin).
So basically, I'm just looking to find out what other people are doing. For the non flashing/modding people, maybe nothing, but for folks like me, I would have to believe you are running into some of the same issues I am.
Thanks (sorry for the long drawn out post)
First point: i charge every night no matter what and plug in whenever there's a charger available, e.g., at home, work in the car. not concerned about battery conditioning, etc. if the battery presents a problem i'll get another device.
Second point: i keep one nandroid, current recovery and my current ROM on my device. this will get me up and running in emergencies if needed. themes and other tweaks can be added later so i don't keep them locally. i can reload apps via Play Store if needed. i keep prior nandroids, TI Backups, system/app and data/app folder backups and anything else on Dropbox. i fluctuate between 2-5 GB of available space on my device depending on how much music i want to keep locally. just keepin it simple
hope this feedback helps...
Yes, except the getting another device part. Not sure if I'd want that expense after plopping 550 for this.
I had a 32gb card in my inspire and usually used about 20gb. Just gonna have to change some habits i guess.

Do your backups automatically upload to Dropbox? If so, how?
If not, ignore this haha.

wanted to clarify my statement. i meant that if i had battery issues, i'd get a replacement HOX. i'm in 100% agreement with you that i wouldn't pay $$$ for another device.

Im debating how I want to do this. Tb has a built in feature for that but it has flaws like if I uninstall an app and delete its backup, it still sets up on dropbox kinda things. Foldersync might be a good solution cause it can do syncing (both ways if desired). Another nice feature is it can delete the local files after uploading to dropbox. It also works with other cloud services. Sorry for plugging the app, but although I haven't really set it all up yet, I went ahead and purchased the full version cause it seems to have everything needed to handle what I believe should be part of any new smartphone that doesn't have a sd card.

hopefully when S-off comes our way and we gain access to the kernal, USB host will be the way to go. I have a short right angle USB host cable and a micro USB drive so I can store everything in my pocket if need be and just save any apps on the phone its self.
Kill 2 birds with 1 stone, Have unlimited space on the fly, and save on Data not having to stream everything OTA

That is a myth, Lithium Ion batteries do not need to be run down all the way. Feel free to charge it whenever you want.

In fact, running down all the way is bad for lithium ion batteries. The reason why some people recommend doing that is to calibrate the charge level circuit on the battery. That said, don't do it too often!
Lithium ion batteries like to be charged often. Charge as often as you can. Keep it topped up.
When uploading short videos, around 1 minute or less, it takes pretty long. Is it my wi fi connection or my phone? My friend had an iphone6 and his video uploaded like almost instantly....
It probably is. Check your connection speed using the speedtest.net app to find out.
