Battery 'Life' tricks

I read about this on a professional site but cannot remember where. Here is what you do:
"To 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 and wait 2 minutes and then TURN OFF and CHARGE for another hour
Your battery life should double. We have tested this on our devices and other agents have seen a major difference as well"
I am still waiting for my phone but I will try this as soon as I get it. I am wondering if this trick applies only to new phones or not? If someone will like to test this please go ahead and give us some feedback. Thanks

no offence but can you tell me how you can charge the device which has been charging for 8 hours? to my knowledge, there are circuits that avoids over-charging in these kind of devices?

You got a point. Like I said, I took this off the net but cannot remember where.

Check out this article: http://blog.gsmarena.com/samsung-i9000-galaxy-s-full-battery-test-ready-–-up-with-the-best/

It's impossible to manage 84h on single charge Or it is possible when you charge phone to 100% then leave it on your desk and don't even touch it.

Im pretty sure I could get up to a week of battery if i didnt use the phone at all. Over night the battery drains 1% max.

standby is quoted as 24-26 days. it's sick. screen on is what sucks the power (in addition to sync and background apps).

for me, wifi uses up 65% of the power lol.

I like to ask, how long have you all had your phones? I think the longer or often you charge your phones the better the drainage power.

ive had mine for two weeks

Don't believe everything you read on the internet..
When I was working at an Apple Premium reseller, I nearly exploded with laughter every day at some of the ridiculous rumors I heard, which were obviously wrong to anyone who sold them, but plenty of major sites were reporting they were likely..
Even now, Kevin Rose (the genius who said that he had seen the iPhone and it had 2 batteries) is still saying crap (which 2 years after I left still seems wrong to me), and every site is STILL reporting it as fact.
A lot of the stuff you read on the internet is untrue. This might be a bit true because of battery calibration and such, but I honestly do question it..

Agreed. After all, if these ridiculous battery "tricks" worked at all, then the physics behind them would be built into the chargers by the manufacturers. Unless you think they are crippling the battery on purpose for no reason? Makes no sense.

Solution to DHD battery problems. Contact HTC!

Hey guys! I'm a new user on this forum and I also a completely new android user, I have just gotten the HTC Desire HD. And I'm really really enjoying the OS. The way you can customize the OS is amazing! And Therefore I feel like I have been missing out for a while.
However there is one single problem about the HTC Desire HD and sadly it's a pretty big problem. (You guessed it,) the battery life. I'm not gonna lie, if i cut some features i can easily get through a whole day. But whats the point of buying a phone with lot's of features if you can't use them, and whats the point of having a 4.3" screen if you can't have the brightness level at 50+.
To the point!
HTC have already made updated batteries that have a much higher capacity than the original batteries, these are for some of their other products.
(just look at the higher capacity HD2 batteries by HTC, they have a higher capacity than the original HD2 batteries.)
That's why i suggest that we all contact HTC and let them know that we are both aware and annoyed by the horrible battery. And then request a better and improved battery for the Desire HD.
If you look at their updates, they have a pretty good history of listening to their customers.
And if their customer service department get about 300 requests in one single day I am absolutely sure that we will see a result in a month or maybe even faster.
I live in Denmark myself and I've seen a similar thread in
a Danish forum and in two days time we have had 183 people send mails to the Scandinavian HTC customer service.
Now there is only about 2000 active users on that forum so that's pretty good for two days. And with such a huge success in a Danish forum, I'm sure a big forum like this would do even better!
So if you have the time to write a little email to the HTC customer service telling them about the poor battery life and then make a request for a better battery, I (and probably every DHD user) would appreciate it.
And even if you are one of those lucky users that can go for days without charging while having standard settings,helping us wouldn't hurt.
Thanks in Advance

Well....although I do get your point, I am not sure that I, and probably other people as well, agree entirely on the 'horrible' battery life.
Yes, at first, it does look to have poor capacity when you get your DHD out of the box.
But remember, a lot of people, if not allm are using their new toy a lot the first couple of days.
If you browse this forum and the DHD topics you'll see that people report a lot better battery life after a couple of charges.
In addition to this, when you get into rooting and flashing, you'll see that users with custom roms, custom kernels and special profiles setup in Setcpu (like less Mhz usage when the screen is off) actually even get better battery life out if their DHD....
In essence, from what I have read, most people are able to use their DHD for one day without charging, which in my opinion, is quite acceptable, considering the size of the screen, the speed of the device and the possibilities and syncing going on....
If I sometimes read other cells'threads, it appears to me that the battery life on the DHD is not that far off, or even is better, than other top devices....
Having said that.....the effort you take I understand for sure, I just am not sure that HTC will do anything about it (as I think what we get is what we should expect)...

Where is the solution in that? Infact there is no solution its how it is

DHD battery life sucks.
There is no point defending it. Its a bloody mobile phone, it supposed to be able to work out of box, not a science project that u have to spend days tweaking it in order to last a day without the bloody adapter!
u can tell i m really crossed with DHD battery life...

It does work out of the box. Did yours not turn on?
If you mean 'it's supposed to have the best possible life the first time I fully charge it on day one' then, no it's not. You are wrong.

I just don't get it this was my first proper Android phone after coming from a HD2 and an iPhone 4 and the battery life is on par with both out of the box however simply reducing the time some apps sync I mean can you really not wait the 2 sec ish Twitter etc take to update? Really does improve battery life I have my screen set to 30% brightness which is more than enough if not you need specsavers not a new battery.
At a push I can get 2 days out of my DHD and I would say I'm a average to heavy user about 30 min calls 50 odd text and a couple of hours playing games surfing the net
Gadget show last night drained an iPhone 4 from full charge to flat in 2 hours using the layer app
I don't use setcpu etc I've just used some common sense.

well, i charged mine overnight, leave home at 7, phone dead most days by 5pm. u can defend the battery life as much as you want, and i m glad u like yours. less than 12hr of standard use makes any smartphone useless in my view.

I use iphone4 along side my DHD, almost identical setup in terms of sync and updates. when my DHD battery flat out in the afternoon, iphone4 has typically over 80% left.
I dont think it takes a rocket scientist to see DHD's battery is an issue.

Unplug mine from charging about midnight, get home from work between 18.30 and 20.30 and most nights I have approx 30-40% battery left, LiOn batteries need multiple charge / discharge cycles to get the best out of them so no phone is gonna be at it's best outta the box.

There seems to be massive difference in peoples experience with there DHD mine defo lasts as long as the iPhone 4 I had how yours can last less than 20% there must be something wrong

mine actually died last night (the first night i had it) i was a little surprised but i checked the battery usage and com.zxing..... used like 70%
lol it seems the barcode scanner didn't close and kept the camera on all night

I am a heavy user Facebook sync every hour a hundred odd texts a day few hours of internet browsing and I can get more than 12 hours mainly like 15 hours unplug at 7.30am and charge it 12.30am

it seems that some people have a very good battery life even with heavy use,and some don't. I am new to android having come from windows mobile. In winmo devices,the radio version on the device can make a difference to the battery life on similiar devices.maybe this is the same case on DHD because I noticed there are several version of stock roms with different built of radio image.

There isn't really a benchmark for "heavy user". I reckon its largely due to different interpretations. Throw the difference in batteries that are likely to exist due to the manufacturing process, and you'd get varying reported results.

why do people complaint so much about battery life of DHD and other smartphone. when you look at their capabilities, you wouldn't switch your laptop on an expect it to last all day. cause its a smartphone doesn't mean it can do everything for you!
if the battery really bad, then the is a fault i.e faulty battery,app which is eating up resources, radio constantly changing from 2g to 3g which i think one of the biggest drain on battery or a set up which just going to drain battery faster etc etc. These phone when "out of the box" are set up to show the phone off, so yes its going to have it all sing and dancing at you! with everything switched on why you taylor the setting to meet your needs. please don't come back and say "but yes why have i got a smartphone and then i have to switch off all these features" you don't but don't expect it to last all day.
sorry about the rant but i think some people just have unrealistic expectations how long a smartphone can last. people who complain that the phone cant last 24hrs, why would you want it to last that long?. you telling me you don't sleep in that period of time if you want a phone to last 2 days get a nokia 8950! an if your a person who uses it as a business phone, come on what do you expect? your a heavy user. use some sense, have it so you can charge on the go or a get a nokia 8950 as your business phone, an use your smartphone as your own phone.

True, but i honestly cant see why it would hurt to encourage HTC to make a new battery with higher capacity as a part of their accessory lineup for the Desire HD.

sorry yeah i do agree with you, that HTC sould bring out a higher capactiy battery and don't understand why HTC have not used a higher capactiy battery in first place. ive also have a X10(1500mAh) and BB storm2(1400mAh) both have higher capactiy, and X10 is the worst for battery life out of the 3 phones and DHD beats both these phone on battery life.
HTC have the reasons why they used that size battery for the DHD and if they do bring out a higher capactiy at least you can believe the claims of it being a 1800mAh, were these 3rd party batteries claim 1800mAh but really you only getting 1400mAh.
i was not aiming this rant at you, an im sorry, its to people that complain about battery life of todays smartphone and there expections of them.

Test it! You must not use more Power per Hour than 1%.If you are at 4% you do something wrong. In standby of course...

For those who have bad battery life...!

Some hints:
1) Flash Bi-Winning V2. Not V3 as I found the V2 has better battery, and V3 doesn't have too many advantages.
2) Keep brightness at low or medium-low. I doubt you need to ever put it on high. If you really want to be smart, use a brightness widget. (the one from curvefish works well
3) Try to have little to no widgets on homescreen. If you must have widgets, use trusted/well-reviewed ones. I installed a clock widget and it drained my battery in 9 hours.
If the above still does not work, then continue. If you are feeling you are getting great battery life, then continue. NOTICE: One major reason why people are getting poor battery life is too much tinkering. After seeing other people are getting better battery life, they try to flash new kernels/modems/roms/etc... and it turns out the new is worse than the old. Then they go and complain. SUMMARY: If you are feeling you have good battery life, then leave it. You should only worry if you do not get at least 12 hours on VERY LIGHT usage. (5 phone calls lasting 10 minutes, Checking emain every 30 minutes. Having fetch for 10 minutes, not push. No widgets, no music, no games etc...​
4) If you still do not have good battery with biwinning v2 flash the BALI UV kernel.
5) If you still do not have good battery, try other kernels. Kernel is the one that mainly controls battery.
6) Do you live in an area with poor reception? Try a modem that has good signal-getting abilities. Searching/switching drains battery.
7) If you still do not have good battery, try other roms.
8) If you still do not have good battery, then there is something seriously wrong. Either you are using the phone too heavily (gps etc...) or your battery is worn down. Get a stock replacement.
9) If you are here then just get a extended battery. There must be something wrong with your phone, so either exchange phone or get extended battery. If you do not want buldge get a 1600 or 1650 mah battery.
10) If you are here then throw your phone of a cliff and get this:
http://marginprice.amazonwebstore.com/Nokia-3390-Himalaya-Wht-Faceplate-Back/M/B001KKZQ4Y.htm
11) If you still do not get good battery live under a rock.
NOTE: EVERYONE'S battery life will vary based on usage and other factors.
That said, I am getting 30 hours usage with 50% left. 20 minutes of gaming, 8 phone calls, checking email.

YOUR tips aren't going to work for EVERYONE else.
Everyone's phone is unique, they use it differently, at different times, it depends on what YOU do.
If your gonna use your phone for HD Graphic games 24/7 its not gonna last 10 hours its common sense.
If your so worried about your battery then you know you should turn off GPS/Blue Tooth/ Turn down Brightness.
It's all common sense.
What i don't like you did was firstly, single out ONE ROM for having the best battery, depending on your usage.
Truthfully, i get 2 days of battery on CM7. I don't use my phone to play games and **** not all the time at least, text, phone, music, news , and browsing is what i use it for.
I forgot who it was i think it was Eugene who said
If you want your battery to last, treat it like your mother, not a piss poor whore.

Could also be because bi-winning v3 is still in beta while v2 is not.

Not starting a flame war but..
Counter-Point 1) I originally stated that results will vary.
C-P 2) Some people have bad battery even with those things turned off
That's all... Goodnight!

Seriously, battery life has to be the #1 topic or complaint on every Android forum about every ROM, Kernel,or Modem. Thx for the tips krackers and everyone else who tried to find a way to conserve battery on these life sucking smartphones we have now days. Also, you're right xriderx66 "EVERY VIBRANT IS DIFFERENT" no matter how you look at it. What works for one person won't work for the other. By now we all should know the basics of batt. conservation, like what to turn off / remove and to o/c or not to o/c and of course the biggest battery drainer which is how long the screen is on or how bright u have it.
My point that I'm trying to make and that I had made on other forums (which alot of people didn't care about) its that we have these phones that could do so much but we constantly trying to conserve battery so we take the goodness out of the damm phones. I wanna have all the widgets I want running, I wanna have my brightness to 100% so I could see it well in the sun, I wanna have my bluetooth on all the time so I dont need to pull my phone out and dirty it at work. I wanna have either my wifi or data on all day cuz ant any given moment I wanna listen to Pandora, go on you-tube, or browse the web without having to switch this **** on or off, I wanna have my phone running like 95% of other Android user who don't even know what the hell a ROM or Kernel is but don't worry about tweaking this or that like we do so they enjoy their phones even though it kills their batteries.
So how do I do it??? Simple.... I went on eBay. I got three t959 batteries for $12 total (with s&h).I got a t959 battery charger for $3.50 total. I got a wall and car charger set for my phone for $5 total. Now I got a phone charger at home,work, and car. I got a battery charger for all my batteries. I got three fully charged x-tra batteries ready to swap whenever I need to (and not the 3500mah cuz I dont like my phone fat). All that for $20.50. That is how much it cost me to stop being obsessed with my battery life and to fully enjoy my phone. I think alot of you out there should think about doing the same so you're not obsessed with battery life. ENJOY YOUR PHONE PEOPLE

How to get a full battery charge and improved life

For those who have bad battery life first charge your phone fully while on then turn phone off...plug the phone back into charger while it's off it will be a red light charge until green sometimes it takes another 20 mins .When done turn phone on and plug charger in again it will drop to 99% when 100 plug out now u have a fully calibrated battery..I am on the new firmware btw

Actually it's not b.s I noticed that around 80% my phone would drop down quickly to 70% and 30% would drop 3% instead of 1 so I did this method knowing that my battery was not fully charged.since I have done this no more quick drops...instead of saying b.s why not try it first then come to a conclusion smh

I can vouch for this ...I am only trying to help those who gave bad battery drain...we do flash a lot on xda sometimes **** happens
HTC ONE rooted,S-Off,SuperCid

Instead of clowing u guys should try it..listen phone says fully charged for some but in reality it is not it will rapidly drop for example 90% but drops to 79% rapidly or drops 3% for no reason while screen is on is due to battery not fully calibrated/charged ..This happens from flashing roms sometimes this happens if you have battery issues try this method ..
HTC ONE rooted,S-Off,SuperCid

I used this method a couple of years ago on my DHD. It made a huge difference! i forgot all about this. I'll do it again later.

Thanks, I had a feeling the calibration was a little off since the phone shuts down at around 5%, let's see what happens.

Yeah, I do this on my galaxy note and sometinmes on my new one.
When 100,% through normal charging turn phone off and begin charge again. It will charge just that bit further.
One thing the note does better is thaat when off and charging you get a battery indicator on screen, not so with the one.

WhatsAUsername said:
I'm pretty sure the only way to get a full battery charge is to hold the phone upside down in your right hand, put your left hand on the back, and spin in 3 circles, counter clockwise. You must then quickly plug the charger (within 1 second), and spin the phone around the cable 3 times, in a clockwise direction this time. Only then can you ever hope to have a fully charged battery.
I can vouch for this. :good:
Click to expand...
Click to collapse
Man that's total bull...... only 2 circles required
To be real for a minute if I may..... if you monitor the current draw by the phone when charging you will see that when the green led lights the phone is still pulling 60-70mA from the charger so it's still charging and can take a while longer for that draw to fall to 0mA. At this point it's fully charged.
Charging it as the OP suggests does actually allow this extra top up.

I actually think this does help with proper calibration a bit. Not sure why people are acting like children here.

The topic of batteries makes people go crazy for some reason. I will toss in my own 2 cents, the thread title talks about improving battery "life". In this case we seem to be talking about "battery life per charge cycle" and people should just be aware seeking improvement in this area usually comes at the expense of a different kind of battery life, ie "battery life per phone".
I personally am one of those who is a little irritated by the non-replaceable battery on the One because I intend to keep the phone for many years. This applies to almost nobody else I realize, but for me this thread is a helpful summary of the exact steps I need to *avoid* if I want to get the longest lifetime (measured in years, not minutes) out of the battery.

What's wrong with turning the phone off every once in a while and letting it charge up fully?

actually i'm totally cool with doing this procedure every once in a while as a way to just what it says, get a few extra minutes of battery life. hell, if very precise runtime estimates are important to you and this helps calibrate that, great. i'm all for that too. i actually *have* tried something like this and my phone didnt die and i'm sure i got a little extra run time that day.
i just wouldn't do it *every* day.
one of the findings in another thread around here (something about battery "health") was the battery ages quicker at higher voltages such as those used towards the end of the charging cycle. if you are willing to constrain yourself to charging the phone to *less* than 80% capacity (ie the opposite of what this thread is about) you will double the useful life of the actual LiOn (or LiPolymer or whatever) material in the phone.
that is all. not trying to discourage anyone from *ever* doing this procedure, just explaining why i actually strive to do the opposite most of the time.
carry on.

Known fact... it is impractical to FULLY charge up a battery while is is in use (hence, being drained). Plain and simple physics at work here and I can vouch for this based on the many years I worked in the Navy charging, repairing, replacing, and rebuilding naval vessel batteries. Granted these are not huge deep cycle batteries but the charging principles are the same.
As as matter of fact, just did the method the OP was kind enough to suggest to us and it worked like a charm. Noticed a higher mv reading on my battery! Not much but I will take it. Who would have figured on that...
+Thanks to OP for bringing this up.
EDIT: For the record, I would normally reach 4310-4313mV... after this I am reaching +4335mV - Not much but I'll take it.

Thanks, I had a feeling the calibration was a little off since the phone shuts down at around 5%, let's see what happens.

That's only because fast boot is most probably enabled...

Known fact... it is impractical to FULLY charge up a battery while is is in use (hence, being drained). Plain and simple physics at work here and I can vouch for this based on the many years I worked in the Navy charging, repairing, replacing, and rebuilding naval vessel batteries. Granted these are not huge deep cycle batteries but the charging principles are the same.

Ahhhh vindication ...
HTC ONE rooted,S-Off,SuperCid

As fun as it is to mock, this most likely does work. HTC seem to be pretty bad at making battery algorithms, never found myself having to do this on the galaxy nexus or nexus 4. But my battery drops to 85 darn fast now and I'm pretty sure this will help. I remember this was helpful on the desire and desire HD too.

A lot of people say this is merely a placebo effect, but I agree that it works very well for me with my device.

Poor battery no matter which rom

I've been using several different 7.1.2 roms and battery life has been atrocious. I use wingoku 4.1.
I pair my smart watch to it but even when I use wifi (no bt) its bad, draining quickly, last checked about 22% per hr. Even with screen off listening to podcasts it still will drop a lot more than it used to.
I really don't have much in terms of stats. Honestly I don't obsess much about it normally but now its noticable.
Aside from suggesting another rom & kernel, would I benefit from formatting data and starting over?

Install accubattery and run it though a few charge cycles, it will be able to tell you the life left in your battery, it's possible that you have the same issue many of us have had with a degradation of the battery.

Yea. Thats my biggest fear. Ive replaced small parts before but my eyesight isn't as good as it used to be so Im afraid I might mess it up. Plus I'll need to buy a heat gun.
I'll be more than a little pissed if the battery's shot. This phone is barely 14 months old. Either give us a decent battery or make it replaceable.
Thanks for the info btw. I just installed the app.

Update--Im switching things up a bit. Recently I made some changes and this time I flashed a new rom without some of those changes.
1. I had switched from Action 3 to Nova
*HIGHLY doubt nova is eating up my battery so Im still using it BUT I did remove a widget that has weather. Since I keep phone on device only location, I think theres a chance its always trying to find my locale and consuming battery.
2. I didn't add a gov profile yet.
3. This is the first time in about 4 or 5 rom flashes I didnt flash CTT Mod.
* Again I doubt this is causing battery issues but Im gonna hold off flashing it. No throttling thus far.
As suggested Ill be monitoring with accubattery for a few cycles. But been using my phone about 90 mins this morning (at least 90% of that time actively using with screen on) and I've lost 13%--a huge improvement from yesterday.

Accubattery for the proof. New battery for the fix. You could always buy online and have it installed locally. Read up on where to score a good replacement battery, rather than another dud.

Thanks. But for now it looks like my battery is ok. I did a follow-up post above. And to follow-up on that, Im still getting good battery life.

Okay, sounds good. What does Accubattery report your battery health as? (health tab)

Its not really giving me much info yet. Because of my schedule throughout the day Ive charged periodically so I have enough juice in case I need it. Do I need to let it run lower to get an accurate reading?

Best to let it run below 20% at least and then fully charge until the APP tells you the battery is full- not your phone. Don't unplug until Accubattery says it is full. What you will observe is that the phone will continue to charge for 45 minutes to an hour past when the phone itself is reporting 100%. You will find the estimated capacity under the Health tab. Once or twice below 20% is enough to get a close approximation. After that it will move a couple percent max. You will know soon enough.

Well it turns out my battery is in need of replacing.
I let it run down like you said. I was going to go further down but once it hit 20% my phone turned off. I plugged it in, opened accubattery and it said 46% under health.
But I just checked again after charging to 100% and it now says 63% (2182 mAh total capacity).
I checked my imei on the Huawei site and my phone is 3 days out of warranty. Im hoping to get them to fix it.

Well sorry to hear that. Good luck to you on the RMA route. If not, the Cameron Sino brand replacement is a bit more expensive but includes a working battery temperature sensor. It will make your phone like new. Note in the thread I referenced above, some parts may get scratched/cracked depending on the skill of the repair person. They aren't expensive so it you are intending to keep the 6P for a while longer, it may be worth it to buy those just in case.

Thanks for the support! I checked that thread and didn't see specific parts (inexpensive ones you referenced) If they're listed Ill look again. It doesn't seem too daunting. I was able to replace the screen on my son's WiU controller. Those were very tiny parts and YES--I did snap off a clip, however I was able to fudge it and it's still working about a year later.
Far as RMA, does anyone know if they replace it with the same crappy stock battery? From my perspective this seems like a clear case where a recall is in order.
But if its the same battery, Im just setting myself up for the same problems 8 to 12 months from now. Even if I buy a new phone Id still want to sell this one and thats not as easy with a crap battery. Plus theyd have my phone for x days so Id need to find a temp phone in the meantime.
Don't mean to jabber on...this sucks.
Oh yeah...cuz it was after hours I sent an email to support last night. Do you think Ill get a response? Or should I just call when I have time to be on hold?

Spoke to a clone at Huawei then asked to speak to the clone's supervisor (wasn't sure if clones had supervisors--they do. But the programming is identical.) Long frustrating phone call and they aren't going to replace my battery because its out of warranty...by 4 f#@&ing days!
I told them they lost a customer for life and I was being 100% sincere. How could I ever buy from people who thinks it ok to sell defective crap, know about it, then do nothing to make things right?
I'm gonna replace the battery on my own. Whether things go good or terrible, one thing is certain--itll be the last time I ever replace anything on any product made by Huawei.
