[HTC ChaCha] EraqEE:
I can get up to 3 days of batter life when the phone is completely idle. This doesn't happen too often so with regular use, I can get up to 2 days of battery life.

Heavy usage gives me around 6-8 hours of battery life, which is still much better than Blackberry phones. My old Blackberry was at 60% and it literally died within an hour of using GPS and turn by turn navigation.

Overall, it's a pretty decent battery life, but it does get pretty hot at times like others have pointed out!
[HTC ChaCha] qbert456:
It *has* to be the dialer app, once some kind person releases a custom Rom this problem may get sorted!

And i told HTC over a month ago so not a known issue?? Really.
[HTC ChaCha] theloginwithnoname:
HTCs ROMs are notoriously inaccurate when reporting battery usage, and I'd say this is one of the worse device ROMs! As you indicate, a cyanogenmod ROM would likely give much more accurate usage stats.
[HTC ChaCha] andoy:
after 23 hours, i have 38% remaining. Does the analog clock affect the battery? I noticed that the hands of the clock always move from 12 to current time when i open the screen.
[HTC ChaCha] andoy:
So my battery was at 8% after 2 days and 8 hours (56 hours). I didn't wait for the battery to drain before plugging it in to charge. From the rate of the drain, I could have pushed the battery to 2 and a half days (60 hours) or even more. I still haven't changed my clock back to analog, using the digital clock widget (was asking this above).

I also read that the dialer is draining the battery as well (issue with gingerbread). Might be true, after disabling the sensors (may be causing the dialer issue), after 11 hours, my battery is still at 100%. I did some texting and even bluetooth and my battery is still at 100%!.
[HTC ChaCha] andoy:
After disabling the sensors for call, I'm at 79% battery after 34 hours! Niiiice, the fix worked, I no longer see the dialer as resource hog even after calls. I did some txting, bluetooth, games, wifi for the past 34 hours.
[HTC ChaCha] ThiloH:
Which sensors do you mean?

The muting after picking up the phone, or something else?
[HTC ChaCha] EpicEric:
I'm curious as to what Blackberry you had. I've had several and battery life has never been an issue. Even when the batt low light came on I could still easily make it through the day.
[HTC ChaCha] andoy:
That's correct ThiloH, those sensors. After switching them off, restarting the phone, i don't see the dialer taking up battery anymore even after calls.

After 61 hours, I have 44% battery even if i did a lot of txting, some wifi, gps searching, bluetooth for almost 2 hours, and some calls.
[HTC ChaCha] iDAREK:
My wife ChaCha... dont stay alive more then 12h :)

Will try this battery, and I'm curious if it change anything :P
[HTC ChaCha] andoy:
I'm skepctic with 3rd party brands for battery. Be careful not to over charge, it may expand and damage your chacha.

I hope HTC makes a higher capacity battery.

Do let us know what happens
[HTC ChaCha] stjepa:
How did you disable the sensor?
[HTC ChaCha] Alex C.:
Go to Settings -> Sound -> Disable Quiet ring on pickup, pocket mode and flip for speaker.
[HTC ChaCha] stjepa:
Thx. Will try and report with results.
[HTC ChaCha] iDAREK:
I dont think thats turn off sensors, becouse they are still working on changing phone orientation or when you call to somebody (screen off) and take your handset out from your ear - screen is on.

This can in some point extend battery life, but I doubt that will be more then couple % (1-3-5)
[HTC ChaCha] andoy:
Works for me, i can now easily get over 3 days (more than 72 hours) even with lots of txt messaging, every day connection to bluetooth for my car, GPS, wifi (ne browsing), and calls.

If it was idle (never tried), i think it can go up to 5 days. Do note that i'm only using 2g, it costs to use 3g in my country, and the network signal in my area is excellent.
[HTC ChaCha] Alex C.:
Basically those are the sensors that everyone is speaking about. The ones I posted above. The screen off sensor (proximity sensor) cannot be turned off from settings.

The screen orientation is a different thing (it's based on the internal G-sensor). The other sensors should be the ones causing such stress.

Also setting to 2G (GSM Only) should decrease battery consumption.
[HTC ChaCha] jporch316:
The point is i think that one or all of these sensors is keeping the dialer running after making/receiving a call indefinatley. The dialer should stop running after the aforementioned call. Hence the extra drain to the battery. There is a thread for this issue (which is possibly gingerbread and not handset specific) on googles android dev site - it affcets quite a lot of other handsets (mostly HTC like desire z, wildfire s - all reporting 90% dialer battery consumption).

The only sure fix is to restart your phone after every call, others have mentioned disabling the sensors as above, and others have mentioned turning on / off bluetooth after every phone call.

It listed as dialer in partial wake log
[HTC ChaCha] musash1:
not working

Hi, all... i have tried everything ... but the dialer is still trying to suck all my battery juice after 1st call of the day! :(

I have disabled the sensors as above and also tried with turning on / off bluetooth after every phone call, i even tried to change profile from normal to vibrate, (as i have red that that also worked at some cases), also soft reset.... but still NO IMPROVEMENTS! :(

i have Juice defender ultimate installed.. but even that cant help me ..

...my battery record is around 22hrs, not even a day. And dont have any battery consuming apps, widgets, no task killer, no battery monitoring apps, almost all default....

I guess its its 2.3.3 prob, as many have already stated...

code.google. com/p/android/issues/detail?id=17383

And Andoy .. .how , how , how is that possible!? x)
[HTC ChaCha] Alex C.:
Probably. I have noticed that on some phones the "sensors/bluetooth" tweak does not work. Mine acts the same way as yours. The only thing I really changed is installing Advanced Task Killer Pro and setting it to low security, aggresive kill mode. My battery is somewhere around 30 hours, but wi-fi is always on (as I need it for work). Have you also set it to 2g? (GSM only).
[HTC ChaCha] andoy:
That's basically it. I also have the screen to lowest (my eyes are sensitive, all my gadgets have brightness to lowest), and disabled the auto rotate screen because it annoys me.

Check your network signal again, as mentioned above, i have excellent network signal so this doesn't eat the battery.

On the average, i have 3 and a half days (84 hours) battery life on a single charge (still have 9% battery left, i only plug in for charging when phone is below 10%). If you don't believe me, come over at my place and stay with me for 3 and a half days.

My usage list is as follows for 3 and a half days:

- lots of txt messages going in and out (total of around 100)

- bluetooth connecting to my car for 2 hours everyday (total of 6 hours)

- wifi for updating my maps and quick browsing (total of 6 hours)

- permanently disbaled background data, i only enable this when i browse

- some calls (total of 5 hours)

- gps (total of an hour)

- alarm clock everyday

- have the missed reminder app installed which makes led light blink forever

- no task killers installed

- not using analog clock in homescreen, just plan digital clock

- using only 2g

That's it. No need to send me private messages, when all info are already here =D.
[HTC ChaCha] andoy:
Oh yeah, one more. Don't say that I render my phone useless with my usage above. This is how I really use my phone way way back (even when i had my win mo phone, SE X2, 1st and last).

I bought the chacha because I love android, I love the form factor, excellent screen resolution. If I wanted a bigger screen (this would only mean no hardware keyboard for pocketability), I would've gone with IPhone (excellent screen and response, sad but true). But I want my hardware qwerty and to be able to touch the screen for games and browsing.

I'd only change my chacha, if someone releases a similar phone with louder (better) speakers. Chacha's volume is too soft.

Don't even mention nokia E6, held it, don't want it. Maybe if they change it to android :D.
[HTC ChaCha] Alex C.:
Weird.. The difference between my usage and yours is:

- no txt messages

- no bluetooth

- wifi on constantly

- background data enabled constantly

- no gps

And I still can't get to 2 days (with sensors off).
[HTC ChaCha] musash1:
Thank you Andoy ! I think i made one huge mistake , i didnt charge my battery for 8hours at the 1st time after it got empty. :( Thats my biggest problem . I talked to htc stuff , and he told me to try and charge it now for 8hours (but he doubts it will help) , and to check the battery with sort of a test , charge it to 100% then leave screen on for 1hour , on max brightness , in airplane mode. And if that shows battery level under 40% , i must change battery. Maybe they will just change it , because its still under guarantee period, only 5 days old ! :(

And btw, i use mine Chacha less then u guys :(

Hopefully this will work for me in some way!

I let u know guys .

Ouh, one more thing , about the dialer, he said , they are workin on that problem/bug, and they will fix it with new FOTA.
[HTC ChaCha] andoy:
I didn't charge my battery for 8 hours the first time. I only charged it for 4 hours. And with the lithium ion batteries nowadays, you don't need to do the over charging anymore.
[HTC ChaCha] musash1:
Ok , here are the things that i figured up, sort of ... dialer is on 7% after couple of calls , but i didnt made those calls, after my first dial, the dialer started again to make trouble , the rest of the story is already known ... :( So the bug occurs only when u make the call.

-i also did that battery test with screen on highest brightness left for 1 hour turned on (on home screen in safe mode and airplane mode) . My battery lost only 3% and dropped to 97% , and my battery's mV is 4210mV after full recharge .

...i thought i did sthng here, but , i was wrong... my brain is full of android *&^%$, if u know what i mean. but i'll post it here for sure.

... and does anybody have the problem with overheating ! mine chacha is heating even when i get msg... dont let me get started about how hot it is when i answer the call or browse .... (and ofc in games, but thats sort of normal, and i dont play them much )
[HTC ChaCha] Alex C.:
What do you mean by "safe mode"?

And yeah, mine's overheating too, but only during calls and games. Otherwise no (wi-fi is always on, connected).
[HTC ChaCha] musash1:
this is what htc stuff sent me:

Please try to: soft reset the phone (take the battery out and put it back again)

Please try to: enter the safe mode on your phone and check if you still have the same issue . You can eneter safe mode by:

Safe mode:

Press power key then press and hold the menu key

1. Press " power key " for power on device

2. Wait until "HTC logo" appears on screen

3. Press and hold " Volume down key " until entering OS

4. " Safe Mode " text will appears on the lower left of screen Safe mode will disable all 3rd party apps and only preinstaled apps will work, this is done becouse some of 3rd party apps can interfier with your phone functionalaty
[HTC ChaCha] musash1:
no solution

Omg, i'm so tired of trying ...! What to do.... Lets say restarting the device solves the dialer bug, preventing to increase its battery % drainage, Dialer remaining on "only" 45%, but i need to reboot every time i make a call.

But even if i reboot , my battery still lasts very short , from 100%, 1 day max, sorry from 11am till 11pm, so its basically half day, sometimes its 16hours if i'm lucky! with display powerd only 4hrs , less then 2h wifi , 30min 3G/Edge (always ff otherwise), 30min games, 10 mins call, 30msgs , 10 emails, no background sync enabled, and no demanding apps, no task killer, battery monitor, no live wallpaper, etc....only juice defender ultimate, so basically only default ones are installed?! Its ok when its on stand by ... i get almost flat battery graph usage for hours , bu the moment i take chacha into hands , it starts dropping ... like i'm doing i dont know what! AND THATS WHAT ANNOYS ME the MOST, i cant use my phone a bit.... its like i'm having the old nokia 3210... only calls and sms , and snake! is it not ?

So with no dialer problem... because i was rebooting,and it stops increasing when i reboot... I STILL HAVE THE DAMN PROBLEM :(( :sad:

My HTC Chacha's performances are pour, which is sad because i really like this phone! :(

Does anybody think so , or have the same problem except the dialer, maybe its GB, or because of fast raise in cell's temperature, which drains battery more..

I mean , i checked the battery, it seems that everything is fine... 4200mV + display test proved it. Dont know what i'm doin wrong....so tired of this... gonna sell the phone...

I even use HTC's 2GB SD card i got with the phone, because i red that some SD cards could be the problem sometimes...

Sorry but duration of HTC's battery for 2 or even 3 days with moderate use, are incredible and unreal for me with or without Dialer problem!
[HTC ChaCha] F0l3ert:
disable the sensors for increase ring on pick up and the two others. this fixes the dialer problem. I've been getting +2 days no problem on medium usage since then.
[HTC ChaCha] Alex C.:
Doesn't work with all phones though :(.

Mine is up for around 24 hours though. Over night (in 8 hours) I have lost only 5% battery in stand-by.
[HTC ChaCha] ThiloH:
@musash1

How a about you bring your phone back to the store, and get a new one?

Mine lasts around 2 days on normal use.
[HTC ChaCha] musash1:
And what should i tell them; Hi my phone's battery lasts very short, only one day? And they will be like; Oh, ok, here you go new one.

... You know how are they , and i told ya, i did the primary battery test, its ok , my battery lost only 3%, and one more thing after 8hrs of standby in air plane mode last night it was still on 100%... And they gonna say "1day?" , well sir its smartphone what did u expect. Every time i take my phone i think of spending less time in Sense for not wasting my battery too empty before day is over, in 12hours straight . told ya 23hours personal best!

Last night i charged the phone to 100%, before sleep i put it on airplane-mode, and after some 8hrs , when i woke up, i still got 100% battery. I turned on the phone used it to send receve 10msgs and 10emails, turned on wifi for email, sync and fb turned on for total of 30mins , (mobile data OFF ofc), and Display was on for 1h10mins... and here we are , battery level on 79% , so only about 60mins of use and i lost 20% , that leaves us , that u can use Chacha only 5hours before its empty and i'm saying with low usage , cuz 30mins of internet eats up 20% .. thats even worse.. so u have 150mins (theoretically) to use wifi ... and its around 120 i gues with 3g on, cuz it consumes more battery than wifi.

And yes Alex C , turning off those sensors doesn't seems to work for all (many) devices. at least for me not, and for most as i could see, i tried all trust me.

IMPORTANT. I received email from htc stuf and talked to them in live chat, and the said that HTC Cha-cha battery issue is already escalated to their engineers and the issue that you are experiencing should be resolved with the next FOTA (update) for our device. The stuff also told me that its the only problem reported for Chacha, and they are very aware of it , because of many appeals and complains on battery power! and he sayd lots of it!

so, all we can do is wait.
[HTC ChaCha] iDAREK:
And for now, is better to use JuiceDefender... becouse even bigger battery doesn't do much better...
[HTC ChaCha] hpdroid:
Then, just wait for the next ota update.

Btw, my battery only last for 1 day.
[HTC ChaCha] qbert456:
Same here, a day, and I mean working day not 24hrs nor from me waking up till bedtime!
[HTC ChaCha] musash1:
Do you guys think that we should try to calibrate our battery as it had helped some of here folks, on xda... check this out: what r your thoughts... ?

[HTC ChaCha] iDAREK:
This is useless, this is li-ion battery not ni-mh. This kind of batteries doesn't need to form or calibrate. This question is backing every couple months.

I test free version of JuiceDefender with data controll off (becouse I need be online all the time), and battery works visible longer on my Desire Z and my wife ChaCha.

Think about some alternative for this, or if I dont find anything, I will think about buy Ultimate version.

Does anybody from you heard about some power management programs that extend battery life? Or some program to create power profiles (without root).
[HTC ChaCha] andoy:
So battery life gets better for my case. Still with the same usage, lots of txt, calls bluetooth, wifi, led lights, alarms, loudest sound....

I managed to get 4 days, 20 hours, with 5% of batt life, i plugged in for charging.

I still see the dialer consuming 94%.
[HTC ChaCha] musash1:
oh man, Andoy, c'mooon! Why are you doing this to us... lol :)

How is that even possible, its longer then the old Nokias phones , that had only calls,sms and snake with green screen... thats even longer then the htc's specifications are telling ... dont know how u doing that , but i wanna buy ur ultimate Chacha :P

..cuz here, mine still lasts hardly one day! with moderate usage and no games, i also did factory reset! ...so nothing changed ... 20hrs only, usually
[HTC ChaCha] andoy:
I think network signal and screen brightness are factors. As i've said before, network signal in my location is really strong so my phone doesn't have to work that hard to get signal. As for the screen brightness, i always have ALL my gadgets set to lowest brightness as my eyes get irritated easily.

I don't have any task killers, or juice defenders, or anything similar as I heard that these apps don't help.

Love this phone.
[HTC ChaCha] Alex C.:
@andoy, I finally got the usage said (almost).

4 days and some hours. Had a few calls, mobile data activated for about 30 minutes when I had to browse something and a few texts; alarm, led lights. Screen brightness is set to automatic.

Network coverage is very important.

Edit: I've started They Need to be Fed for 5 minutes during which I've lost 10% battery, which is a lot! During the night I lost about 3% in stand-by.
[HTC ChaCha] andoy:
Yup, same thing for me, overnight stand-by without use is between 3-5% loss only.

By the way, when I said using LED lights, I meant using apps like missed reminder. HTC phones have that blinking LED light notification in front but for some reason, it would stop after 5 minutes (you can test this out) after receiving a text, a missed call, etc. What the missed reminder app does is that it keeps the LED light blinking continuously and infinitely whenever a text message or missed call, etc comes in. It would only stop once the notification has been read and closed.

So my battery usage includes this LED light blinking for hours if in case I left my phone, etc. Which shouldn't affect the battery at all but is still a batt usage =).
[HTC ChaCha] ceoxm:
If just standby,chacha can less 30% power in one day(14 hours,turn on 3g,no phone,no sms);

If use some programs,just like brown the internet,the power cut off so quickly,less than 1.5 hours.

I am so disappoint about chacha battery!
[HTC ChaCha] Alex C.:
Switch to GSM mode only. 3G eats more battery.
[HTC ChaCha] andoy:
For those who are still encountering battery issues, go to running services and stop facebook chat. this might help.
[HTC ChaCha] Luggruff:
For those of you getting over a day from the battery: You're lucky. Smartphones like these usually last a day at most with active usage. That's the way it is, plain and simple. You can't really switch up to something better.. at the time being.

And battery (and performance) is also affected by the amount of stuff you put on the home screen, and how many home screens you have.
[HTC ChaCha] knowsnophones:
Any update yet on the updates to the battery life?

With the tips in the thread, will I be able to get 16hrs of battery life with 2 hours worth of calling and 3G data connectivity?

How is this phone's battery compared to other Android devices out there?
[HTC ChaCha] EpicEric:
Just got it today. Charging...
[HTC ChaCha] jporch316:

[HTC ChaCha] knowsnophones:
With data always on, how many hours do you get?
[HTC ChaCha] Alex C.:
I don't know really and cannot test since it would cost me a lot for the transferred data. As I have Wi-Fi almost everywhere (work, home and city center) mobile data is used on a very rare basis (emergency cases usually).
[HTC ChaCha] chuday:
HTC Cha Cha, bought it on Sunday, everything was within my expectations such as performance, battery, choice of compatible apps etc.

to further share my battery information, i'd say i am a frequent user

H/3G alternating data around my area (hong kong) on, with 1-2 hours of mp3 music, frequent messaging (100 messages in whatsapp/gtalk), brief phone calls ~25minutes, light web (tweetdeck).

official battery 1250mah lasts 10hr 30m (of course 90+% dailer)

preparing the bump charging method

will be ready for tomorrows test

report tomorrow
[HTC ChaCha] knowsnophones:
When you mean alternating data 3g, sometimes it's on sometimes it's off? Is background data on?

How much browsing?

Can't wait for y our next report. I'm sure it will be informative

Thanks. Really nice one.
[HTC ChaCha] chuday:
to Report back on my findings

official Bump charged battery to have lasted 1.5hours more

totalling to 12hrs of use with same intensity.

my verdict:

1. bump charging to me does work, but the increased in battery life may vary it seems.

2. even if you gotten a 1600mah cell, i doubt 1 battery will suffice for the above usage.

summary

well if thats the case, wether fixing the dailer bug or bump charge, you'll need another battery should you want to go (charger-less).

---------- Post added at 03:17 PM ---------- Previous post was at 03:15 PM ----------

everything to do with data is on(alternating between 3g and H is just the inconsistent network coverage, since HTC cha cha is a messaging orientated around messaging that should be common practice to be on "listen mode" for any whatsapp/ebuddy/gtalk
[HTC ChaCha] Drabir Alam:
Tried with Two ChaChas

I tried one Cha Cha and then changed it for another. Both has the same dialer issue. To help things, I have reduced screen brightness to 20% and have shut down data and wifi for most of the time.

Sincerely hope HTC finds a fix soon because I am in complete and utter love with this phone apart from the battery issue.

Anyone has any idea on the dialer issue? I have been following all the threads in xda and other forums for the past few days.

Now slowly drowning into despair :(
[HTC ChaCha] Mowgliro:
Dialer

Hi, everybody !

I have the same disturbing problem with the Dialer thinggy ! :mad:

Mine goes nuts only after an outgoing call.

Installing any of the three custom ROMs would make this nightmare go away ?
[HTC ChaCha] alsaidy:
Sorry Musash1 i know how you are suffering concerning the battery life. Please try the following i have seen somewhere in this forum but i cant find it any more thank i have copied and save it in word.

"To also help with Battery Life you can do these steps exactly:

1) Turn your device ON and Charge the device for 8 hours or more

2) Unplug the device and Turn the phone OFF and charge for 1 hour

3) Unplug the device Turn ON wait 2 minutes and Turn OFF and charge for another hour Your battery life should almost double, we have tested this on our devices and other agents have seen a major difference as well"

These are consultation from HTC people i tried it and it works for me. Please try it and let us know.
