Hello, I've recieved my AT&T Tilt 8925 (Kais100) unit a week ago and ever since I've experienced awful battery performance. The item shipped new (not refurbished supposedly nor defective) and included a Samsung battery. I changed to Dutty's v3 ROM right away (flashing was successful, I also switched to radio version 1.27.12.27) and last night switched to Q-Mobile v1.2 to see if the ROM was the problem, but it persisted.
My battery drains extremely fast, even when the unit is off it drops 10% after 8 hours (overnight and also throughout the day, I'm leaving the unit at home while I solve this issue and it's always off). The unit does not have a SIM card inserted and the Phone function remains off, so does WiFi, Bluetooth, Beam, 3G, etc. It's also muted and has no alarms activated, nor background programs running (I'm currently running a freshly flashed Q-Mobile v1.2 ROM with a hard reset done as well).
I've read about battery perfomance extensively but haven't ever read about the battery discharging while the unit is off, and given the fact that I'm NOT using the phone functions, I barely believe this can be normal behaviour. I purchased 2 units from the same source and both are having similar issues with battery perfomance.
I'm currently testing a borrowed OEM Dynapack battery from a friend's Tilt to see if it shows the same behaviour as well to discard the possibility of a faulty unit. Note that I'm using the OEM 1A charger and leave the unit charging for several hours.
If the battery proves to be defective I'd have to get one (or contact the seller to see if he'd respond to the issue). Can someone recommend a cheap/reliable battery that could be bought online (eBay, etc.)?
Thank you very much! I hope that someone has a clue on this issue.
Best regards
Sebastian
Just to clarify, is the phone actually OFF, or is it in standby? If it's in standby, 10% after 8 hours wouldn't be unreasonable at all.
Uhm, it's on standby I guess (when I turn it on again it's instantaneous, not like when you soft reset the unit)...
I'm new to PDA phones, I had an IPAQ RX3715 before with WM2003SE and I could leave the unit off for days without battery drainage. However I may not be too familiarised with these new units' standby/off functioning. If in standby and with the Phone function off (meaning that the device has "nothing to do" other than being off) it's normal for the device to drain the battery so much I would be disappointed.
As a sidenote, my friend's Tilt is not draining while it's on standby being on the same conditions other than the fact that his unit has the Dynapack battery.
Regards!
Bat Drain
I have the same rom and the same problem. I was at the hospital all day i made two calls and about mid day my bat was at 30%. I think its duttys rom V3 causing the problems. Changing roms now.
I could be wrong, but I think your phone is fine, these devices just consume a lot of power. 10% over 8 hours would be totally normal in my opinion. Is that the main reason that leads you to think there is a problem with your phone? Have you ever had a pocket PC before that had better battery life? When I got my first PDA I thought the same thing, but I realized that they are not like normal cell phones, where you could just recharge once every couple of days. PDA's must be charged at least every night. If you use GPS or wi-fi a lot you're probably going to be charging sometime throughout the day as well. I just got into the habit of plugging it in every time I get into the car, and when I get home I plug it into either the computer or the wall charger. There are after market batteries available, but if you want a drastic increase in amp-hours, the battery is going to be bigger and it will require a new battery cover. This is totally unacceptable in my opinion, as the device is relatively large to begin with. My advice would be to only activate a radio if you are using it, and de-activate it when you are done. Also just get into a routine where you are charging it whenever possible. Another thing, I just flashed Dutty's V4 RTM, and I must say the increase in battery life was very noticeable. Don't let me confuse you, though. From the information you supplied, I really am not able to tell if there is a problem or not, so give some more information and examples of battery life so we can figure out if somethings wrong, or if you just aren't used to the amount of consumption of this type of device. Hope I could help. Cheers!

Yeah that's not normal. You got any radios besides phone running throughout the day?
Thanks for your thorough reply. Picking on what you mentioned, it's true that I'm new to PDA Phones, as I mentioned I also own an iPAQ rx3715 with WM2003SE and my idea was to replace it. Judging the fact that PDA-only devices, to my eyes, are nowadays dying I thought I'd get me the latest and most complete device available WITH GPS, since I was using my iPAQ together with a GPS Bluetooth Receiver with much delight.
What I experienced with my previous device was that battery performance was never an issue, it did consume power as any PDA, but I didn't find myself worrying about it, it never dropped when off and it would last me several days.
Since I'm using my Tilt with the Phone function off I _thought_ it wouldn't need any power for anything... but it might be that these new devices, or the new WM6 architecture is different to that of WM2003SE/PDA only devices... I don't know, but it just sounds strange to me, although if it's normal I'll live with it- as you say, I'll have to be charging it 1-2 times a day.
On the one hand it would be good for me to know that my device is ok, but on the other hand it means that battery life isn't even close to what I expected... I had read people complaining about it but in general I tend not to be overly critic about the defects of devices... but it seems that it's the case. I meant not to use the phone features and thus I thought it wouldn't be consuming power on standby seeing that the phone should not be running anything on background...
Thank you again for your reply. If anybody else has a word on this I'd appreciate it.
Best regards
Just as an aside you will notice the battery life getting better after a couple weeks it seems the battery has to be conditioned so to speak. Also do you have any kind of push email on your phone as if you do that does use quite a bit of power, you might want to set it up as a pop3 account and set it to check emails every so often instead of getting them as soon as they come in.But I have amde it a habit to always use my charger whenever I am able to as these batteries seem to be happiest when topped off whenever possible.
Hello again, I'm still experiencing this problem and it seems not normal.
Simply put, I fully charge the device. I turn it off. It discharges by itself with all wireless functions off.
Today I did a hard suspend (keeping off pressed) with battery at 60%... when I turn the unit on 7 hours later the battery was at 6% with a critical warning sign.
I'm NOT using the device, I turn it on, use WiFI for 3-5 minutes then switch it off and put the device to suspend. I turn it on after a couple of hours, play with the menus and turn it off again. Just by doing that the battery drains by 10% every 5 hours or so, sometimes it won't even turn on due to battery drainage.
Is this NORMAL? I need to know if my unit or my battery is defective so I can return it to the seller in time...
Thanks, best regards
Sebastian
Battery life DOES seem to improve with time. The first day my battery wouldn't last for 5 hours! Keep charging your battery and letting it drain as much as you can (whether or not to let it fully drain is debatable), and I bet you'll see some guaranteed performance.
Also, what would help a lot is if you found and installed the Today plugin BatteryStatus and checked the "Show More indicators" option, and see what your battery drain was. The normal is between 150mA and 300mA when you're on the Today screen. Any more than that, and you most likely have a problem, assuming connections besides phone are off.
sounds normal to me, turning off you mean by pressing the button on the right side of unit? if so, mine is the same way
I'd say that was definitely not normal performance. On average, I use mine for at least an hour worth of talk time, an hour or two running TomTom, numerous SMSs, and at least a couple of hours reading books. I charge it every night, and the battery is generally running at around 50 to 60% by that time. I'm surprised at how quickly yours is draining.
I have an RX3715 inhabiting a drawer, and, while the battery life was a lot longer on that device, the battery was a lot larger, and the screen lower quality. The fact that it is not connected to a mobile network gives the battery a much longer life too. When I used it purely for TomTom, connecting to a bluetooth receiver, the battery faded very fast.
I've had a Kaiser since day one. I have found that adding a comm manager that allows forcing the phone to Edge give huge battery savings. In standby with the phone radio On and BT radio ON, WiFi OFF, my phone drops 4% over night very consistant. On Edge battery lasts days.
The only time I get fairly high battery consumption is streaming with 3G. Edge is so much more efficient on the battery, so if you don't need the speed, throttle down!
The only time I've ever found the phone Dead or close to dead after only a few hours on standby was when I had WiFi ON and the phone in standby. I can't pinpoint what exactly causes the condition, but when it occurs, the phone is HOT and the battery heavily drained in a short time. This has happened with both Hermes and Kaiser. I never leave WiFi ON when not needed, and have never seen severe battery drain since.
I do sometimes turn off all radios except WiFi, and then use wired ear buds and stream Slingbox video to the phone over my home WiFi LAN. I can get almost 4 hours of watching on a charge.
The battery should not be draining when powered off, but not much at all when put in sleep mode. Get yourself a replacement Testing.
As an aside, Alex's WM 6.1 BETA 2 has given me the best battery life of any rom. Only about 25% of the battery drains per day. With most other roms it's 50-100% per day.
Hello, thanks to everyone for your replies. It's strange because I've been doing lots of test, switching batteries (I have 4 units to test now) and I get inconsistent results... the 2 most problematic units were bought from the same eBay seller and got their ROMs changed the first day, the 3rd unit still has the AT&T ROM and was apparently not draining as fast. The problem is that the 2 first units seem to get battery drains overnight in flight mode of 10% and 2 times one of them got a 0% critical battery status just by being in standby and not in use (none of them are working as phones and have the function off)
The odd part is that for some reason this happens only sometimes, now I've switched to Sleuth's WM6.1 ROM and the problem is gone for now, I'm still at 90% since 2 nights ago having turned on GPS and WIFI for 5 minutes each 2-3 times... the other 2 units have been in standby from 100% charge and they haven't dropped either! And they're using the AT&T ROM and Q-Mobile v1.2 respectively... what kills me is that I cannot say what's wrong, cause I've swapped batteries, swapped chargers, swapped ROMs but cannot trace which is the problem (or if there's a problem at all)...
Perhaps it's normal for the unit to sometimes drain 10% after 8 hours of standby in flight mode and on other times remain at 90% for 2-3 days if not in use...
Thanks everyone for the read, I'd appreciate any comments
Regards
Sebastian
What radios are u using. Try changing radios
10% loss overnight in standby would be normal.
Does the unit get warm when you notice rapid drain?
I wonder about the "old" active sync problem - does the device show any running programs when you turn on?
In general you should expect to get a days worth of power using it for the odd call, perhaps an hour of wifi and perhaps an hour of prgram use. Of course all taht is very variable but I generally get away with a charge once a day. Occasionally, I take it from it's holder and it's warm to touch, but usually it's 'cos I've forgotten and left something like tomtom running.

i am one of those anal people who likes to keep his battery in good condition by always letting it empty completely before recharging and i have noticed alot that i run into a situation where i need the phone fully charged for some reasion or another but dont have the time to sit around with all the nic's turned on waiting for it to die. i have seen a battery discharge feature on some devices that will rapidly drain the battery to 0 so it doesent develope memory when you plug it back in i was wondering if anyone has made one of these for the raphael?? any links would be apreciated.
i have already rtfw'ed and searched everyone seems so obsesed with prolonging battery life not draining it so i have had no luck
You are actually doing more damage to the battery draining it all the way then if you'd just charge it when you can if you are indeed doing this every single time.
All HTC devices use a Li-ion (Lithium Ion) battery, which do not get a charge memory in the cells like rechargeable batteries of yesteryear.
Instead their life cycle is based on number of discharges and recharges and the batteries age. If you're needlessly discharging your battery and recharging it, you are dramatically shortening it's life.
You should read up...
http://en.wikipedia.org/wiki/Lithium_ion#Advantages
...they may be irreversibly damaged if discharged below a certain voltage.

Like many rechargeable batteries, lithium-ion batteries should be charged early and often.

Lithium-ion batteries should not be frequently fully discharged and recharged ("deep-cycled"), but this may be necessary after about every 30th recharge to recalibrate any electronic charge monitor (e.g. a battery meter). This allows the monitoring electronics to more accurately estimate battery charge.

It is clearly stated in the Fuze manual that it is SUGGESTED that you fully discharge your battery and fully recharge to get the most out of it.
thanks for the advice i will look into it but i would still apreciate someone answering my origional question as to wether or not anyone has actually made one of these apps

This is almost certainly suggested so the battery meter maintains a good calibration. As GldRush points out, you are not doing any damage to the battery or shortening its life by short-cycling it. You could also harm it by deep-cycling it. Allowing the phone to go to 0% is not, however, deep-cycling the battery. For the phone, 0% is the point at which the operating voltage of the battery has dropped to a level that is approaching the lower limit for the board set (with a safety factor included). That's almost certainly nowhere near a discharge level that could damage the battery.
So if you want to let/make your phone go to 0% before every charge you are probably wasting your time (except for the slight benefit of frequent battery meter calibration), but also probably not harming the battery.
After the 2nd battery warning notification comes up, I end up just launching youtube and running a video. The use of 3g coupled with video playback gives me an auto shutdown of the unit with 5 mins or so.
Turn on the GPS. That should drain it in less than an hour.
I haven't seen any discharge apps but I do know that the biggest battery vampire is palringo...start palringo and join a group with a lot of members and your battery will drain at least 20% in about 10 minutes...even if there are no conversations going on you will still get a dramatic battery drain running palringo in the background
Haha, or use an older version of S2U That drains your battery like crazy too.
Way to discharge a full battery within an hour:
- Start Wifi and let it stay on (no need to connect).
- Start Bluetooth and keep it on (also no need to connect).
- Open Google maps and let it use GPS
- Put Google maps in the background and start playing Teeter.
it's almostly no necessary......

These batteries actually get hurt by completely discharging - you're not supposed to do that - you'll kill the battery by bringing it down to 0% too often..
(but to answer you - that's easy.. turn it on.. this phone's a battery hog..)

There's an interesting artice in The Reg about lithium battery maintenance (albeit more related to netbook and laptop batteries).
http://www.reghardware.co.uk/2009/05/07/beginners_battery_maintenance/
not needed, but just run palringo and google maps while listening to music streamed from di.fm in Kinoma. (pretty much what I run day in and out )

hello, is it a common problem? or is there a problem with mine? Not actually very hot, but hotter than the room temperature
I have the same thing, especially if the handset is charging through USB from my laptop.
I don't recharge from USB as I've read that it is bad for the battery. Again, not very hot. Also slightly hot when using UiFi for a very long time, or playing a lot. I guess it's normal. Being used a lot ... :-? I don't know, just asking
Hi georgeono,
I can't remember how to disable charging on connectivity to the PC. Can you please point that out to me?
Many thanks,
Ayman
Hey, I already found it. Don't bother yourself )
It's Settings -> All Settings -> System Tab -> Power -> Battery Tab
And why would charging through USB be bad??
well, to make a good charge, you should leave the phone 5-6 hours (even though the led is green, I let it even up to 10 hours (charging at night)). When at PC, I don't think you all the time keep the phone pluged. In order to make a good charge, the battery has to be nearly empty (new phones work well without this waiting, but still, in time ... you see the differences). And I don't think anyone waits for his phone to be empty to connect via USB. .
I previously had an SE 850i (4 years used). Always charged when battery was empty, charged about 6 hours, and now, in stand-by, the battery resists 10-11 days. That is something ... 4 years!!!
It's normal,the battery heats up when under heavy use/if charged. It's nothing to worry about
Thanks. Had the same opinion, but still asked. never know ...

This is a myth for lithium rechargeables
Lithium type batteries do not mind when they are charged, and topping them up is perfectly fine. Topping up little but often is probably going to extend the life of the battery if anything and not reduce it, why? The biggest killer of lithium type batteries is heat, and giving it a charge from nothing to the maximum means it gets opportunity to get very warm which ages it, whereas lots of little charges will not up the temperature nearly as much.
Also another myth, you can't damage lithium batteries by overcharging them, this is because the current is stopped when they are fully charged as if it wasn't they would explode!
Lithium batteries also have a use by date, and as soon as they are made they start to age and reduce in capacity, so you are better off using and abusing the battery to get as much from it as you can, as age and heat will probably kill it first.

My device is very hot when charging... Much hotter than my Touch Pro2 gets
i experienced a few times that my compact V (topaz model from T-mobile) freezes while using navigation software in the car, meanwhile charging... When i took my phone from the holder, it was extremely hot! After holding it in front of the airco for a while and restarting, everything worked fine again. Anyone else with the same problem?
I found out, that using GPS uses the battery extremely.
It drains with about 300 mA, while normal usage ist at <70-80 mA and standby even a lot less.
Additionally I found out, that the device becomes sluggish due to processor-Usage of nearly 100% (while using gps).
That might be what you are seeing.
Regards Thorsten
talking about GPS usage, when ever i'm on iGo when i minimize it to make a phone call, it doesnt connects. i had to exit iGO n wait a while before it is available to dail. or a quick soft resets solve it.
any of u have the same problem?

Hi
Got an extended battery for my G1 a few days ago from ebay.
The problem is, the phone doesn't recognized it after I switched the battery. I had the same charging % as the previuos battery right after I changed it (even though I never charged it) and the max use time in Battery time lite is the same....
Any ideas ?
Thanks,
Nati
bad phone ? my ext batterys work fine from ebay
is there any way I can be sure ?
Maybe it a firmware thing ?

I had similar issues when I first got an extended battery (Seidio 2600mA). After performing the steps below, I had no problems at all. I hope it works for you.
Try a COMPLETE drain and recharge cycle, a couple times.
Run the battery down until the phone shuts itself off, restart the phone and let it run until it shuts itself off again. Repeat until it will NOT boot anymore. This will take a surprisingly longer time than you think. Load up your music player, youtube via 3G, etc... kill that thing.
Once the batter is so dead that it can't even load the splash screen for a boot charge it up, but do not turn it on. Let it charge up to full for a few hours (usually four will do it) and turn it on. If it's not at 100% yet, let it charge for a while longer. When it's at 100% take it off the charger and run it down again like before. Run it until it is totally dead.
After a couple cycles like this, you shouldn't have any problem with your phone and battery giving accurate charge status results and operating as it should.
I've read, from a few sources, that between the internal monitoring on the battery works, and the way the G1 reads the battery state, that this complete drain and recharge cycling helps to establish baselines for "empty" and "full" and keep them synchronized. If your phone has never seen an extended battery and the battery was at partial charge when inserted, it may not have been able to accurately gauge the minimum and maximum extents and give faulty readings based on prior battery data.
That could be wrong, and I don't know for sure. But, a complete drain and recharge never hurts anyway, and in my case it actually seemed to solve the problem for me.
Good luck!

Hello,
I have an Ativ S and about a week ago the battery started to drain very quickly - about 15 to 20 per cent an hour.
I do not have wifi, bluetooth or gps on and usually the battery lasted 2 -3 days but now I need to recharge twice a day.
I thought that this was maybe caused by a program so I reset my phone and reinstalled only a few programs, but that did not work.
1) Is there any way that I can see if an app is draining my battery quickly?
2) Could this be a hardware problem? If so, how can i tell if it is the battery or the phone? I think that my warranty has expired, so returning it is not an option.
PS It is on GDR2, no interop unlock or any other tweak whatsoever.
Thanks
I'm not going to say it's flat-out impossible for an app to drain your battery that fast in the background, but it's not far off. If you want to be really sure, though, enable Battery Saver mode immediately after unplugging the phone (at full charge) and don't use it. Battery Saver prevents all background app activity, so there won't be any apps running and therefore they *cannot* be affecting the battery.
I'm pretty sure that, given the rate of drain and the fact that it persisted through a hard reset, you have a hardware problem. The good news is that it might just be a bad battery - that is a thing which happens, and it's even fairly common on batteries a couple years old - in which case it's a good thing you have a phone with a user-replaceable battery! The way I'd test that is to swap your battery into somebody else's ATIV S and see if the problem persists. If so, it's the battery; if not, it's your phone. Alternatively, you could just buy a second battery and see if that helps.
One other thing to check: if the battery really is still working and the phone is draining it that fast, it'll be dissipating a lot of energy as heat. Does the phone stay abnormally warm while the battery drains like that? That would be a sign of a problem with the phone or the OS, as opposed to the battery itself.
Oh, and I'm pretty sure there are some battery diagnostics and charging statistics located in the Diagnosis app (##634# in the dialer). I forget the code for them but I have all of the codes written somewhere; alternatively, you could do some searching. You could compare the reported battery capacity there with the expected (design) capacity.
I reset my phone again, installed only Viber and till so far, the battery drain seems to have disappeared (or at least improved).
Some users on wpcentral reported that they had major issues with battery drain caused by Whatsapp.
I used Whatsapp for quite some time but never had any problems( till now).
Maybe the last update caused this, i dunno...
Anyway, thanks for your answer.
I will see how it goes and I will let you know.
