App to drain battery - EVO 4G Themes and Apps

I was wondering if anyone had a good app to drain the battery. I have heard that with Lithium Ion batteries it is a good idea to charge them to 100%, drain them, charge it back up, wash, rinse, repeat a few times in order to get the battery to the maximum amount of life.
1) Is there any truth to this practice?
2) Is there an app for this process?

From what I was told on other forums is the exact opposite. It is the old batteries that had what was called a memory and would not hold as good of a charge over time. I was told lithium ion actually works good when giving little charges here and there and does not need to be drained. I don't remember if I was told that here or on howard forums.

its called 4g on jk but thats what they say

It's really not needed with a lithium ion battery, but some people still feel good doing it. There is an app called Screen Test. Once you load that you can switch to an all white screen at max brightness. Play some streaming music in the background and that should do it

This is absolutely true. The only thing a full discharge does for you is increase the accuracy of the battery meter.

what i did, was set my hero so it wouldn't turn the screen off, connected to my WiFi to get internet, and have music streaming till it dies, I've done it twice already to my Evo battery, I've got my hero battery in my Evo for now

Just to actually contribute, I'll confirm what jeffrimerman said. The memory effect is most seen using Ni-Cd batteries, and somewhat (very little) on Ni-Mh batteries. Lithium Ion batteries actually aren't good to drain completely every time. Charging here and there, or even leaving your phone on the charger should, in theory, have absolutely no negative impact at all on the battery.

Raphael battery WILL NOT DIE

It's been at (!) for probably about half an hour... I'm getting tired but I am wrong... Stupid good batteries, why couldn't you be like the Diamond
It might be the Software, I dont have Pro yet but my s730 will go ! at 40% of battery life and warn me at 20% and go critical at 10%... I would assume your's is doing the same type of thing to keep you informed?

why would you want to do that?? i thought that with new lithium batteries it's better for them to charge them as much as possible, whenever possible. and AVOID them to go to 0. That could kill it, for good! Someone please, tell us if i'm wrong. These are not the oldschool batteris with "memory". So no reason to get it to reach zero for any reason, than destroying it. (it vould need kickstart after that)

Haha yes... Well, I constantly used it yesterday (obviously)... Always connected to wifi, always connected to Edge/3G (depending what was available)... Played teeter, talked on it, browsed the internet, listened to some of the music that's on it, it was being pushed hard... And it lasted like 6 hours. Not bad at all, and it gave me like a half an hour window after the battery went to (!) status.

Li-ion batteries do not suffer from the "Memory" issue as much as others, but they still do to some extent. The biggest issue with all Li-ion batteries is once its charged if you leave it on the charget you will burn it out and it will stop holding a charge.
Running it to near zero before charging wont hurt it, I have done it for almost a year on my s730 without issue and I charge it every few days due to use.
There are rumors that running it to full zero can hurt it and you should keep it charged since it wont hurt it memory / overcharge wise. I usually but not always drain my phone to 10 - 20% before charging to full and taking it off the charger once full. This way I can keep it charged and not worry too much about memory issues.
Ni-MH batteries really sufferd from the overcharge and a little from the memory, while Li-ions are supposed to not suffer from either I have (over retail experience) seen them suffer from both issues as well however it takes longer for the problems to crop up usually.
As long as you are carefull your battery should last a good long time.
I am wrong

Poor Battery Life on NS?

I'm going to try to purchase my Nexus S before class tomorrow when they open. Don't want to take any chances on it selling out. Would it be wise to turn it on and use it a while during the morning? Or does the battery need to be fully charged before using it to condition it and ensure a good battery life? I've read many battery tips but i'm still a little confused on whats better for a new battery.

When you get it, deplete it, but do not let it die. Ever. Then just cycle it normally.

Yes, by letting your battery "die", per se, you're letting it deplete to 0%. I'd say for safe measure, between 5%-9%. But if you're in the vicinity of a charger take it down to 2%. If not, turn it off at 5%, then plug it in before powering it back on. My devices' daily life lasts so long (on all devices I own) because I properly know how to cycle a battery.
If you let your battery die (0%), it'll lose more and more charge (on a 0.00% level) every time. When you get it tomorrow though, it should have ~50%-60% charge.

Battery life?
So how are your batteries doing? Mine is kind of crappy. What supposedly changed in 2.3? I see no difference in the reporting of apps in Battery Use and they took away Battery History in the hidden system settings. Where is the graph everyone talked about?
You gotta give it a few charging cycles for the battery to reach it's full potential. Give its few days, you'll notice it will get better after you charged it a few times.

The battery life on mine is chugging along pretty well. I gave it a full charge before hitting the streets. Its been 4 hours with wifi and GPS on with a couple dozen pictures taken and a bunch of apps dl and installed. used maps 5.0 and periodically hit the GPS for my position getting really good accuracy while driving and the battery level still has a little more than 4/5s battery life still remaining

That's funny because every company that sells back up batteries tell you to go through 4-5 full cycles before it reaches its potential. I guess you're right, and they're all wrong.

how do I train my battery it was halfway charged when i got it do I let it die and then put it on the charger thanks!
EDIT:WRONG SECTION DELETE THIS MODS!
I've always charged all the way up then ran the battery all the way down, then charged all the way up again. Then periodically, I will run the battery all the way down just to give it a little exercise. So far out of all the cell phones I have had I have had 1 battery go bad on me, that was 8-10years ago.
Battery

matter of opinion really.... I would kill it by playing with it.... then do a full charge
that is what I am doing
Generally the suggested method is to charge it for 8-12 hours as soon as you can, then use it until it gets very low, then charge for another 8-12 hours. Do this cycle about 3 to 4 times and you've got yourself a healthy battery.
Killing the battery entirely, despite popular belief, can have some negative effects on its health. Especially during is conditioning phase.

No, It doesn't affect the phone at all...correct me if I'm wrong, the Nominal Voltage is 3.6v for the standard battery which charges at 4.2 volts. The operating voltage is 4.2v (fully charged) and 2.8v (discharged) That being said, your .1v makes no difference to the phone!
Does anyone have a good source to get these cheap?

I needed something on my screen that shows the percentage of battery remaining, I used it with my Nexus One, it works quite well with the Sensation too. With the Sensation you have to put in the battery mAh when changing batteries. How accurate is it? If you look at the screen shot above with the standard battery it show's 8:35 hours of talk time, if you look at the specs of the HTC Sensation at the HTC site, it show's up to 500 minutes which is 8.33 hours. I looked up the talk time on the EVO 3D and it st states 560 minutes or 9.33 hours, considering the Sensation might be a little more efficient, 9:46 hours might be spot on!

Netflix will do the trick. I used it last night to drain my Anker battery. It was at like 35% & took 45 minutes of streaming over data to kill it. Great way to get that first discharge out before you finally charge it up to 100%

I'm going to be devil's advocate for a minute. There's no way to tell the capacity of a battery by taking a snapshot of its current state. If you are telling the app what the mAh is and the battery is charged to 100% then it's making a calculation based on what you told it. It's not actually measuring the true capacity. The only way to determine the capacity of a battery is to fully charge it, then fully discharge it through a load and measure the current. There are no shortcuts, or apps that can do this instantaneously.
As indicated in several other threads the mAh stamped on 3rd party batteries are very unreliable. If you buy a real HTC EVO 3D battery then I'll say it's probable that the mAh is close to the rating, and your test would indicate you may well get more run time on the Sensation. If you buy some other battery then YMMV.
It is good to know that EVO 3D batteries will fit though. Thanks.

You know, I was just thinking abut that same thing. I was under the impression that you had to put in the estimations yourself. I wanted to use it, but I did not know how reliable my guesstimations were.
I use Juice Plotter. It does not do the breakdowns like the app in the picture, but it does a good job giving you a guesstimation. Once you charge it and unplug it it will tell you how much battery it perceives you have left. I primarily use it for the battery drain graph. That is the most accurate thing about it.
Nevermind. Please delete.
that app looked nice so i downloaded the lite version to try with my anker battery see whats the estimated time ...i had this battery for about 4 days works very well and lasts way longer then stock battery very please with anker battery, maybe some one with a CHICHITEC 1900 should check what results he gets

Massive battery drain with heavy use!

Before I start, I'm actually fairly happy with the battery life on the sensation. Today it's been off the charger for about 4 hours and I'm still at 97% with little use and some light browsing. So for general such as idle and browsing, it isn't bad.
I have noticed, however, that the battery life sucks when doing intensive things, such as gaming. I lose easily over 30% an hour when watching videos or playing games. The other day I was sitting through a boring meeting, so I played a tower defense game I had. I had about 60% battery life when I started and my phone died in about an hour and a half. My screen brightness was a bit higher than it should have been, but it wasn't full.
I understand it will drain a ton with heavy use, but 60% in less than 2 hours is insane. I took a 25 minute car drive with navigation and my battery dropped over 20%. That's just crazy.
Has anybody else experienced this? What percent/hour do you lose when gaming? It basically means I can't do much gaming or I'm at risk of my phone dying before the day is done.
Bro, what u think gone happen gaming for an hr, with its big screen on that long? Nothing u said I find abnormal from my experience with this phone, are my last 4 phones. Heavy use = drain
Yeah, I realize that it's gonna drain a lot with gaming. At the same time, I don't think 40% an hour is something to be expected. I'm hoping it was just a weird battery cycle.
yeah, i played plants vs zombies and the battery died real fast. However cut the rope doesnt drain the battery that bad. Depends on game but most phones have poor battery life when you do intense stuff.
the nintendo 3ds has a much bigger battery and also has a poor battery life. Battery technology is crap.
...batteries drain faster under heavier loads bro.
Duh!

I actually am really liking the battery life on my sensation, just was in a joking mood. Coming from the EVO 4g i get twice as long with my S4G. Think about it though, you have a 1.2,3,4,5,6,7,or 1.8ghz cpu, depending on Overclock or not, Massive screen resolution, awesome game graphics that take every bit of the CPU/GPU to run them. And it's All running from a tiny ass battery. Look at laptops... If you play a system taxing game for an hour your battery will be toast, and that battery is a lot bigger. I think for what it is, It does a good job.

Battery Calibration Debunked (By Actual Google Android Dev)

Dianne Hackborn - 6:42 PM - Public Today's myth debunking:
"The battery indicator in the status/notification bar is a reflection of the batterystats.bin file in the data/system/directory."
No, it does not.
This file is used to maintain, across reboots, low-level data about the kinds of operations the device and your apps are doing between battery changes. That is, it is solely used to compute the blame for battery usage shown in the "Battery Use" UI in settings.
That is, it has deeply significant things like "app X held a wake lock for 2 minutes" and "the screen was on at 60% brightness for 10 minutes."
It has no impact on the current battery level shown to you.
It has no impact on your battery life.
Deleting it is not going to do anything to make your more device more fantastic and wonderful... well, unless you have some deep hatred for seeing anything shown in the battery usage UI. And anyway, it is reset every time you unplug from power with a relatively full charge (thus why the battery usage UI data resets at that point), so this would be a much easier way to make it for away.

Is that what wipe battery stats does? I have never noticed any difference when I did that. To think of all the times I have run the battery down, cleared the stats, charged it, and cleared the stats again with no noticeable results.
Sometimes it seems like the battery life gets thrown off by flashing a new rom. It isn't necessarily getting worse battery life but the indicator will work funny like it will show 99% for 3 hours and I will think I am getting great battery life and then go to 30 in the next 20 minutes. It is like the UI gets confused. My tablet will sometimes say "connect your charger" even though the battery and indicator are 100%.
I don't think people realize how much drain the display is on the battery. They flash a cool rom and use it a lot and then think they are getting bad battery life because the display has been on for two hours while they play with it. It is amazing the amount of difference I get between when I am fidgeting with my phone while I am at work (have to recharge during the day) and when I am at home on the weekend and it sits on the kitchen table most of the time (it will generally go all weekend without a charge).
Wonder why its even an option to wipe battery stats with apps or recovery if it doesnt do anything. I never saw a difference myself, I just wiped them periodically cause others seemed to think it made a difference.
Always worked for me. Been flashing since g1 days. whatever

Ya well she helped make the original rom for your g1 so she must be wrong. The thickness of some peoples head

First of all those of us who actually knows about Android OS really knows that /data/system/batterystats.bin is nothing more than stats audit. Now if you think you can't actually re-calibrate battery and project that data than your a fool. It has nothing to do with that file.
First of all to accurately predicate it you need a true daemon that's capable of tracking system data with full autonomy access. Second you need correct battery specs from the manufacturer. As reading memory from it may or not even be supported by the device kernel if its not allocated. Thus you see issues with cross link batteries on stock roms, but some is exceptional with similar size, specs.
Now to project the correct data from ~1-100% you need to fully discharge for it to cycle. Yes I know some of you maybe saying never fully discharge Li-Io but if you know the min mV rating then you can stop near suggested mV as it won't go below and damage cells. From then the duration of full charge is defined along with total available mAh. By calculating discharged -mA draw pre scale unit over empty estimation you can predict the true battery percentage.
Ex: ATM my uptime is 14h 47m at 65% with moderate usage (talk, txt, web). Since I have MP1650mAh battery I'm currently at 1072mAh. As its drawing -90mA per scale unit with 4156mV. At this current rate fully projected empty estimation is 9h 38m. Keep in mind my deviceis highly optimized and is on very aggressive battery saving mode.

And that is why you don't allow fools to use Google. Do you actually understand or comprehend what was said? Let me ask you this why do you think they "wipe batterystats"? What's the reason for it? lol he thinks you can't predict actual mV/mAh of battery based on mA draw lol now that isfunny. The whole reason of having any UI battery metter was based on what logic? Next time you Google.com something make sure you actually comprehend what was the logic behind it. Hey all THE truth is out there...

The sad part was I was backing up on what you said. Calm down read it in lame mans terms before you trip.

Man, its getting hot in here. Lol.
Ok, so, if wiping battery stats is useless because it does NOTHING to the battery, is there a way to address the battery and force it to allow a slight overcharge on a regular basis, thereby shutting charging off at a higher capacity?
Please forgive my ignorance gentleman, and refrain from verbally bashing me.
I bought a 1550 mAh Anker battery. If I charge it to 100% and then use it, it stays at 100% for hours. Is this because my phone is waiting for it to drop below 1400 mAh, or what? If that's the case can I somehow tell my phone to consider 1550 mAh 100%?
I ask because of the mugen power app on the market. It intrigued me. Though there is a chance its a bunch.of balogna.

sorry I knew that was another possibility, my mistake. I thought the link you posted some how undermines what I said as you quoted me. As I only posted how to accurately predict and report battery data. Also I think you know who I am...

That is THE prime reason people "wipe batterystats.bin" thinking it would fix staying for hours at 100% delay and heavy drop in short time. Which is sign of missing true data. Normally its measured via min/max mV and available mAh. Now by subtracting the used mA per scale unit the empty estimation is calculated. Thus projecting power draw at given duration and near accurate battery metter.

So with this being said then you don't have to worry about your battery percentage between flashing roms?
The battery life should be still accurate?
I have a 1700mah

Yes, of course it is the prime reason. My question was, is there a way to tell the phone that 1550 is 100% or do I just deal with inaccurate monitoring that is based on a 1400 mAh battery?
Or, alternatively, will android figure it out over time and adjust for me?

answer me this: why in miui does the hardware led light up green when miui tells me im only at 90%? when i check the mv with the battery calibration app it tells me im at 4220 which is a full charge...what makes miui not see that the battery is full?
Before battery calibration, regardless of what happens, I was getting 9 hours, light usage. After battery calibration I get 19 hours, medium use. I'll stick with it with my thick headed self.
