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

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.

Hello,
I am using my hd7 from the past week...The WP7 OS is pretty good, but i have some issues with the phone's hardware in general.
The battery is pretty weak, it does not even last a whole day, with moderate phone/web usage via cellular data connection.All my updates are off, push email is off (download content set to manual), Find my phone is off, the automatic updates are off as well. With all those options, my phone hardly lasts for 10-12 hours
The second issue is with the speakers. It is too low, i keep on missing calls all the time as I am unable to hear my phone. I have the sound enhancer set to dolby surround, don't know if it works for incoming calls...Anyone experiencing these issues?
My phone is charging overnight. Took the phone off the charger around 7am and didn't have to put the phone back on the charger until 10pm. I have the wi-fi on, making 2 or 3 phone calls. Not sure why your phone is discharged so quickly.
@utopia, any idea how many charge cycles your battery has been through?
In general I have gotten very good battery life with my D3 (as long as I have a signal that is...) but I've noticed one definite thing that really seems to suck down the battery... bluetooth. On my D1 I always left bluetooth on all the time because I have it hooked up to the SYNC system in my car for music and using the phone. On that phone, the battery usage window never really showed bluetooth attributing to any usage... but on my D3 it will consistently show that bluetooth has used 25-30% even when I'm not actually using BT!
Mainly I like to leave it on out of convenience so that it auto connects to the car as soon as I start it up... But even without every being in the car and having the phone on battery with BT on, it will drain from 100% to 50% in about 5 hours without really touching the phone or making any calls... just sitting on my desk at home with full 3G signal. How is it possible that it's using this much power for BT to idle?
Anyone else seeing this issue? Or better yet have a solution aside from turning BT off?
I had the Bluetooth on all the time with my Droid 2, granted I was running custom roms since the day I got it, but Bluetooth did not take nearly any of the battery my droid 3 does. I can still get a full day on the Droid 3 but Bluetooth is taking over 30% of my battery every time.
Is anyone else having bad battery life after the update? Cell Standby and Phone Idle used to draw most of the power before the update, now they're low on the list however Android OS is eating all the juice now. Android OS gets up to almost 70% usage overnight and the battery drains a good 30% or more just sitting idle for 6 hours.
I installed a program called watch dog and it's telling me that "Base System" seems to be the culprit with lots of CPU use, particularly when the phone is idle. I've tried a variety of things like uninstalling recent apps I downloaded, disabling the 4G and 3G radios, trying airplane mode, changing settings, etc. and nothing has made a difference. Really want to avoid trying resetting to factory default.
Have you tried recalibrating the battery or tried bump charging?

Since I use my nav dock in my truck to stream Pandora over my stereo, it gets charged several times a day; however, Android OS is now my big drain as well, where it used to be idle or screen using the most. Since unplugging exactly two hours ago, it has drained down to 70% on the stock battery. (I only use my extended battery when I will be away from a charger for a long time. Makes the phone too thick for my pocket to be comfortable.)
On a seperate note, Google Voice now hangs my screen as well when listening to voicemail. Hey, at least I don't get the random reboots and power ups... :what:

I doubt calibrating will fix the issue because I don't think that's the problem. A system process appears to be hanging and causing the CPU to run constantly. Maybe a bad update install?
Either way I used to get much better battery life before the update. Never had any of the random reboots or many issues with data like others.
My battery life seems somewhat worse after the update. Everything else seems somewhat improved.
My battery seems about the same if not slightly better after the update.
I do a few things to conserve battery which really conserve the battery.
1. 4G off unless I need it.
2. Battery mode set to 'maximum battery saver'.
3. WiFi sleep policy: When screen turns off (although I think the maximum battery saver will turn it off automatically)
4. Display brightness: 0% unless I need it.
i don't know if it was always this bad but i don't think so... just noticed that my phone drains battery like crazy on idle.
it was my main phone for 3 years so it was not staying idle as much but i think i would notice it from overnight drain if it was this bad.
i charged it to 80% then found it at 15% after 12-13 hours, i didn't touch it at all... i'm losing about 5% per hour
tried factory reset, debloating evenwell crap, uninstalling google apps that i don't use as well and didn't install anything yet the drain is still same. installed accubattery and it shows over 120mA consumption on idle, screen off... my new main phone drains around 20mA for example.
https://imgur.com/L16JjXW
this problem started after a battery replacement i think. the original battery was dead, it was rebooting at around 50% if i play a game or launch the camera... i had to replace that battery and those problems are solved now.
according to accubattery(it's pretty accurate imo) the capacity of the new battery is around 2650mah
and side button flex is replaced since my power button was faulty. did the service do something wrong? is there anything to explain this battery drain? maybe they didn't reapply a new thermal paste for example so cooling might be worse but i believe it shouldn't matter on idle. and i can't think of anything else...
edit: tried airplane mode and idle consumption was 22mA, anyone else had a similar issue?
edit2: tried mobile network active but wifi turned off, still 22mA i think wifi is draining like 100mA on its own...
okay i'm like 99% sure its a wifi problem.
when i turn off wifi the drain is normal if i turn on a hotspot from my other phone and keep it reaaaally close then drain is normal again. but if i put it far away drains over 100ma again. even worse if i leave the room and there a wall between them.
also i can connect to my router's 5ghz band but it always disconnects, can't stay connected. aaand it can't see my other phone's hotspot at all if i turn on the 5ghz hotspot.
i hope they just didn't connect the antenna cables properly and didn't permanently damage anything, can badly connected antenna wires cause a problem like that? i wanna be sure before opening the phone. i don't have proper glue yet i'll have to spend some money on it. don't wanna waste it if it's not something i can fix by reconnecting the wires...
