In addition to my other issues, refer to thread http://forum.xda-developers.com/viewtopic.php?t=43272 (ERROR: ITWriteDisk - An internal error occurred), I have noticed that battery meter on my 8125 flashed to the the imate aku2 rom, is always at 100%. I'm unsure whether this will effect charging since when I plug in the charger, the led turns green immediately and stops charging, and I have had the device turned on for 4 or 5 hours disabling all the power saving features, leaving the backlight on, turned on BT and wifi, and its still at 100%... either its a great battery, or somethings screwy.
small update.
after about 5 hours the battery meter started to drop quickly. Although this is good, the problem that comes up for the first 5 hours, you cannot charge the device as it thinks the battery is full.
Am I the only one experiencing this?
same here.... after 24 hours battery meter droped from 100 to 94
bafore it was 90 after 24 hours
maybe they improved something.. thats why it does not go so fast as before
I think it is the fact that the new rom seems to be much better with power consumption. I am getting almost a 50% gain between charges due to my pattern of usage!!! Very happy!
I'm more then happy at the battery improvement, what I am not happy about is that if this is a bug (granted there is improvement), the problem becomes when charging the phone, so I have it for 12 hours, its still showing 100%, I have an offsite meeting the next day, and would not be able to charge the phone for the entire day, the battery will start to drop very fast since the phone thought it was fully charged, when it really was not... I'm confusing myself here, but I think you understand what I am saying.
Also, while my battery was at 84%, I did a soft reset, when the phone came back up, it showed 100% battery and refused to charge... this is a problem.
You might want to inquire about a replacement device or battery - in case it's not the sotware.
My laptop has this issue. It's always been on external power and somehow that's weirded out the control circuit telling the machine how full the battery is. It will read 100%, but it's actually at 75%. Then if I disconnect it, it will go down to 5% in 8 minutes. However, it will happily run for 3 hours+ on that last 5%. Similarly, if I hook it back up to the charger, it goes to 99% (leaving the battery indicator light amber) in another 8 minutes. Takes many hours more for it to get back to 100% (making the battery indicator light blue).
With any luck the control circuit will be in the battery (I believe it is), and the easiest way to check is to exchange your battery for a temporary new one and see if the problem goes away.

Agreed.
If you think your battery is stuck - just do this little test.
Turn on Bluetooth, WiFi, make a GPRS connection, and set back light at 100% and don't let them turn off or let the unit power off. The battery should drain pretty quickly in this senario.
I thought mine was stuck, but it dropped 5% in less than 10 min in this mode.

I'm not so sure its the battery.. another issue that I just noticed, is taht even though the backlight is turning off, the screen itself is not turning off after the designated time I set...... this is rather bothersome as if I forgot to manually turn off the screen.. it remains on constantly.
Even with my original Qtek 9100 EN ROM, the screen doesn't turn off - only backlight. If you want the screen to be off, you'd need to go to Standby, or use a third party utility to turn the screen entirely off.
Although lithium batteries are best kept at a full charge, they should be periodically drained to recalibrate the fuel gauge.

I was also having this problem but after about 2 days use it began to go down. My G3 device seemed to hang at 100% and drop quickly after it hits 25%. I believe this must be a hardware issue as I now have a G4 (setup identically to the G3) and it does not have this issue.
i am having the same issue but i believe it the battery because my phone 8 months old and if you read the battery thread it has all the same issues your having
Hi there,
just a short question. I've update my Diamond to the naked version of the official 2.03 ROM (can be found around here) and the radio 1.09.something (that quad band radio with supposedly good battery life and gps reception).
After a clean hard reset I only installed powerguard to measure the drain as a reference (so I can compare what installations of some programs might do).
I was shocked to see that the drain was 167mA out of the box with 3G already disabled, no WiFi or anything running. Is that normal? The auto brightness kept the level at around 5/10.
I was able to bring it down to 64 by disableing auto brightness and lowering the level to 2/10.
When the brightness dimms completely I get 53mA.
Are those values that are normal for a Diamond? Those 60-70mA with lower brightness would at least give you some time to work with the device but at ~170mA the battery drains like nothing and would be flat in less then 8 hours (the 1340 battery that is). You don't work with the device constantly but the drain out of the box shocked my quite a bit.
Yes, thats our beloved Diamond alright.
Well, around 60-80mA are workable and much better than the close to 200mA out of the box. But I wonder where HTC got the claim for stanby usage from. Standby (with display off, just sleeping away there) my Diamond consumes 15mA. Using the standard 900mA battery would keep the Diamond on the net for 60hours. Using the 1340mA battery this increases somewhat to 90hours.
The official claims are in the 300+hour range though for phone standby times. That would mean that the drain would be as low as 3mA. Where on earth did HTC measure that???
The 1340mA battery should give me 2 days of Diamond before needing to charge (mainly standby, some data tranfer, little WiFi and GPS) and that's not much worse than my old Eten X500 was able to do with its 1500mA battery.
with extended battery and 3g off, i am able to get a weeks (7 days) worth of odd phone calls, a fairshare of txt messaging, a little bit of gprs, no gps. If i turn the 3g on the extended battery lasts around 3days with a fair bit of usage.
I think its just the phone, no matter what powersettings you have its just power hungry. I went through many different power settings, roms etc to finally find something not as hungry and what free'd up ram
Lets do some math here -> 7 days would mean roughly 160 hours. With the extended battery (we're talking about the 1340 one do we) you're average drain would have to be as low as 8-9mA - including the spikes when you do some work. I think that's highly unlikely given the fact that the diamond usually does never fall below 10mA just sitting there on standby. Usually I see values of 12-15mA during that state.
Doeing work once in a while and making some calls, I'd say my average would be around 30 giving me barely two days of usage.
I simply rely on the base 900mA battery as backup so far. It's light to carry around and when my 1340mA one is done I quickly change them and get another couple of good hours. At home I recharge both. Battery changing is done very quickly on the diamond and the rubberdized back of the 1340mA set holds the stock 900mA just as well (so I don't have to carry around two back covers). This way the 900mA stock one also gets trained and does not sit idle in the case degenerating over time.
And since the 1340s are relatively cheap atm (I paid 25 Euros for one including the back cover) I may end up simply getting another one of those. Those two and the stock would get me through the work week and on weekends it's recharging time.
I can't really remember how the old phones did it. My first mobiles would last two weeks on standby and my first Qtek would achieve 1 week. They did not have larger batteries did they?
The Diamond is not particularly power hungry though. I ran some test on the HP messenger (914C that was) of my coworker today and this one has a large battery (close to 1900mA as far as I remember) but struggles just as much to get through two days, maybe even more so then the Diamond as the 914C seems to drain even worse. And the oh-so-hip iPhone 3G (we have three guys at work with those) barely gets through a single day. Those poor souls always carry a charger. Guess modern devices are just hungry for electrons.
Another question is about the "training" of the battery. The usual consensus is that the battery need a couple of cycles to reach its potential. But who does this work mathematically/electronically? The drain values don't get lower as they are system depentend and the battery does not generate more capacity then the 900mA or 1340mA. So where does the extra runtime come from???
Some more observations...
1.) There has to be something wrong with the PowerGuard app. Either the measurements are rubbish or the Diamonds can fall into some sort of deep sleep when not used for a longer time that PowerGuard is not aware of.
I recharded my 1340mA yesterday morning (that was over ~40hours ago). I used it through two full working days now with normal usage for me (2-3 shorter phone calls a day, some download using Edge and some WiFi and some 15min of GPS each day). Now I'm at 40% battery. That would even get me a third day of usage like I need.
Not sure if the power drains measured by PowerGuard are higher than reality or if the Diamond goes into some sort of deep sleep when not used for a longer time with even lower drainage then the 12mA.
Whatever I'm quite happy to see that the 1340mA will give me two full days of heavy usage (for my standards) or three days of standard usage.
2.) The Diamond drain is relatively good compared to other devices. We did some more tests today at work and especially the HP models drain their battery much faster resulting in shorter life then the Diamond - and they have 1900mA batteries.
We did equal tasks on the devices and the "drop per task" on the Diamond was better then on comparable modern devices. Some older ones are way better though including older HTC models that some of us still use.
Hey,
I've got a few questions I'd like to ask the Xerpia commuity. I'd like to say that I love this phone since upgrading from my SG2. I have the Xperia Z from T-Mobile and look forward to creating themes for it.
1. I see that some people have mentioned setting the bightness slider to a certain level and using the auto brightness function when they work to save battery life. How does this help in saving battery life? Is it setting a level for the screen not go below and then letting the sensor adjust more brightness if needed? I usually set my devices to 1/4 of the way with sensor off thinking the sensor measuring light would be an extra drain on the battery.
2. I'm new to this device and the only hesitaton to get it because of the built in battery. I've owned plenty of smart phones to know the battery life is truely dependant on how you use it; use it more and battery drains faster etc. There was no expectation that this one would be any different. Has anyone had good results using an external battery pack to charge the phone on the go? If so which brand would you recommend? These things have dropped in price over the last year and I'm considering getting one to take on trips or events where having access to a plug wouldn't be a real option. Many of them claim to charge phones 2 or 3 times on each charge (depending on size of the batteries at play of course).
Thanks

Good questions.
Personally I use the brightness slider at about a 3rd with the auto on, I also have a toggle in the drop down notification that dims the screen on touch, you can find that in settings - display - quick settings. I find my battery life to be perfectly acceptable, it lasts all day as long as I don't do any serious gaming or massive uploads/downloads.
As for external batteries I personally have one of these...
http://www.amazon.co.uk/KingMansion...tery-Xperia/dp/B00EOKQ5E2/ref=pd_sim_sbs_ce_2
It's 4200mAh so a decent amount more than the Xperia Z itself, 2330mAh if I'm right. It isn't too expensive at £17 (don't know what that is in foreign money). It fits well and charges the battery at about the same rate as the mains charger except it's through the pins.
The Z has a great battery, it could be better but then what phone has a perfect battery. Just don't go crazy on the heavy usage, you'll destroy the battery in minutes, 40 minutes on GTA:Vice City and my battery is gone.
Hi
From couple days I have strange problem. When I use my phone, screen starts to get brighter and brighter and after that, some thin brighter horizontal lines start to blink all over. Next what is happening- screen freezes or goes black so I have to restart phone. After that battery goes drastically very low - from almost full to less than 15% (sometimes even 1%) and after that everything repeats: 1% - bright lines- phone restart by it self or freezes. I am using custom roms and kernels, but alwas had cpu set max 1200mhz to save battery.
What is wrong? Is it the battery or something else?
battery.
Thanks. So I think that I will going to buy some battery with bigger capacity as my christmas present.

The first day I had it, I woke up around 8:00 AM and got to about 6:00 PM when it ran out of juice. This was with heavy use, screen always on and brightness set to about 60%.
I changed the settings so that the screen is not always on and brightness is now set to 40%. This made a huge difference. Today, for example, I've already had it off the charger for 8 hours and it's still at 79% battery. I'm at work, and it's getting used as it normally would be.
The screen being set to always on will obviously burn through battery at a fairly quick rate, especially if the brightness is set high. It's worth noting that letting the screen turn off automatically does not impede its usefulness. The screen comes on automatically when your turn your writes to look at the device, and when you touch the screen.
100% @ 7:30 a.m. & @ 31% battery as of this post, 9:20 p.m. with heavy use throughout the day. I had the screen @ always on through the majority of the day; however switched to off @ around 7 p.m.

Screen off for sure. It comes on automatically when I go to look at it, and I want to conserve battery.

Undocked at 8 AM with 100% charged, used till mid night with heavy usage with 32% left when got to bed. Very impressed with battery performance. I am using default settings (brightness - 4, Always-on screen, showing cards on dimmed screen, alert on watch and phone when connected).

Unplug at 7:30am @11pm still 49% battery but my note 3 battery goes down, i have to plug it in the afternoon.
My battery usage on my phone shows android wear being the main culprit.
Before that, I could last all day in one charge.
unplugged at 8a.m. plugged back in around 1:30a.m. about 18% left.
Screen set to "always on", brightness set to "4".
I'm not sure what constitutes heavy usage, but I do look at my screen and do a couple of swipes about every 15 minutes or so, unless I'm expecting an email or something.
Why do you need the screen always on?
The screen on when you look at it functions really well, and saves a lot of battery.
I unplug at 6.45 am. Still got 60% by 10.30 pm

Wow, guys, what am I doing wrong?
I take mine off charge when I get up at 5.30 AM.
It's down to 85% by the time I leave the house at 7am (it's maybe had the screen on for a total of a minute maximum).
I lose roughly 10% an hour (with maximum "screen on" time of a minute or 2 an hour.
It's below 20% by 3 or 4pm.
So I thought it might be that I had brightness on 4/5, so I've changed to 1/5, but still, it's little better. I might get an extra hour maybe.
I like the idea of it, and when it's alive, it's great. But for me, I'm struggling to get 10-12 hours, with low use.
i'm gonna try it tomorrow with Screen-off mode enabled.
I'd happily accept charging it every night, but I'm struggling to get half a day here.

There's definitely something wrong there. I would try unpairing and resetting the watch (the only thing you'll lose is fitness data).
Then I'd uninstall Android wear from the phone, reset the phone and start all over again.

Gonna try that now..........
i agree, there's something not right in your situation.
i took mine off at 11am and it's almost 3am now and i'm at 43% screen always on and moderate use
Got mine on Thursday. Since then it's off the charger for 16h/day. Setting is always on. Indoor I usually keep the brightness at 1 since I really don't need more. Outdoor it's always at 5.
I always end my day with 20-30% left.
One thing I noticed is colourful watch face kill the battery. Specifically while driving since the brightness it at 5 at the screen come on often while driving or doing other activities.

Having reset the watch as suggested, It does seem greatly improved for me.
It came off charge this morning at 7am, so by now I'd normally be down to maybe 30-40%, but I'm currently still on 82%.
Thanks for the suggestion - it looks like it may have solved it.
I'd normally end the day with about 50% left. Two days ago I installed Pinterest and Fancy to see what the interface is like. The next day I ended the day at 7%. Today by around 4pm I was down to 30%.
i uninstalled both apps, charged it up, and the battery usage seems to have gone back to normal.
On my watch the battery is not that great comparing to some of you. Have you activated some battery saving options ?
Mine comes off charge at around 7am. By 10pm I'm usually around 25-35% battery. Usage is light to medium, with screen set to always on at default brightness.

i think it generally comes down to how much you interact with the watch. while i have somewhat moderate usage, the interaction time with the screen fully lit is fairly short, a majority of the day my watch is in the low power screen state (b&w mode) and i think that prolongs the battery quite a bit since it is a samoled screen and i'm sure the processor drops down to a low power state.
a lot of my use is swiping away notifications and navigation (but while in navigation the watch is mostly in the low power state since it shows my next step on that screen)
I'm not interacting that much with it, but each time I turn my wrist, the screen turns on, and I think that's the problem. The B&W mode is nice, when I just want to use it like a real watch the B&W mode is sufficient, is there a way to stay in B&W mode when I turn my wrist, but still have the vibrations on?
Thanks.
