I just received this in the mail yesterday, and I think that it's worth $30. The battery definitely lasts longer. I'm only on my first day of use, but have had the phone on with normal use and bluetooth on all day (9+ hours so far) and I'm at 60%. Had I remembered to turn off bluetooth this morning, it would have been closer to 70% left since the bt accounted for 21% of total battery usage.
Also worth noting... The wall charger seems to properly charge the battery. I drained my original 1500mah EVO battery down to 7% and then placed it in the charger. It charged for approximately 6 hours. Normally, when charging it from empty in the phone, it charged much faster. I'm not a battery expert, and I also could be mistaken, but I get the impression (from reading threads and using the phone and previously owning an iphone) that the HTC software is not properly charging the battery and that is contributing to the miserable battery life right out of the box. Obviously changing setting in the phone software help quite a bit, but I feel like this charger and battery setup help significantly. I'm going to throw the fully charged original battery in tomorrow, and see what kind of performance I get out of it. I'm betting it will be much improved.
Apparently I can't post links on my thread because I am a new user. Just search ebay for chichitec and check out there store. I'm not affiliated with these people in any way. I just happen to be pleased with their product and figured I should share this for any other users that are frustrated with battery life on their EVO.
I just got it (though from another seller).
Figured it was worth the $20 to see if a different battery can help my situation.
I'm at 24 hours up time 3 hours of awake time and still have 26% left. Plus I've got two fully charged spares. Battery problem solved.
Did you actually get red batteries?
They're not exactly the same with the HTC logo, but they are red.
What are the eBay item numbers you guys used?
This is from the same seller for one battery and the charger. He basically charges $10 for each item.

And I am convinced that the poor EVO battery life (stock) has to do with using the phone to charge the battery. I charged the original HTC battery with the included charger and I am at exactly 40% battery remaining with 24:37 up time and 3:05 awake time.
So much better than before.
That's why people are using the method from the forum where they charge their battery 10 times to "condition" it. That definitely helped me, but using this external charger is even better.

Are all the people who brag about 24-31 hours battery time sitting with like 3 hours of actual up time for that period? if so no wonder i dont last any where near that i am usually done at 12 hours with about 6 hours up time.
I consider 3 hours over 24 hours to be very light usage just wondering if that is the reason why no matter what i do i ant get any where close to some of these peoples times.
I wasn't trying to brag. I was just happy to finally get what I consider to be a great improvement over my original battery life. I wish I had more time to use my phone that many hours in the day. Seeing that I don't, this setup works good for me. I know this isn't amazing battery life given my light usage, but so much better than stock out of the box. I haven't rooted yet, and I'm not very conservative with settings that drain the battery.
And to answer your question, yes, that's why your times are shorter, but it seems like you should be getting more. If I have a day where I get more up time, I'll post the numbers.
So most people are familiar with the seeming "bug" that if you slap in a huge extended battery (Seido 3600mAh one comes to mind) if you are charging via USB it would only charge up to the 50-60% mark
I'm seriously thinking about getting a sprint extended battery - but does this bigger battery suffer from the same "problem"
I know this one is Lithium Polymoer instead of Li Ion... does that change anything?
All I know is that I refuse to take my battery out every 24 or 36 hours to "wall charge" it directly.
Thanks in advance for you input!

Mine has been charging perfectly... have had it two days, and it's been great
thanks for the quick reply -- I'll try and pick one up here in the next few days. I'm sure I can take it back if the huge back or if i had any charging issues
would be nice to go 24 hours and not have to worry about the battery at all
I have loved it... i have been able to actually use my phone.... and i even had them credit me $20 for buying the battery
You could have posted in the thread in this section, just a few posts down. But to answer your question, I have not had any issues yet. I know it drops by 3-4% a little quick (30 minutes - 1 hour) but that is the only major drop I see.

Li-Po is actually not going to change anything except that you can put more cells in the same size battery, therefore increasing the length between charges.
Most of the LI-Ion batteries used in phones are LI-po now adays anyways. The orignial evo batteries are. and most of the extended batteries are as well.

Actually, they haven't used Li-Ion batteries in most consumer electronics for several years but the name has become a generic descriptor for an entire family of cells which include LiPos.
The complete name for LiPo is lithium-ion polymer and they differ from lithium-ion cells in several ways including:
The electrolyte in a Li-Ion cell is a gel (liquid) while the electrolyte in a LiPo cell is a solid polymer.
The layers in a Li-Ion cell need to be tightly compressed so they're typically rolled and housed in a tight-fitting cylindrical case, but the layers in a LiPo cell don't require that compression which is why they can be manufactured in that handy flat form factor so easily.
The nominal working voltage of Li-Ion cells is 3.6V and it's 3.7V for LiPo cells.
LiPo cells have a higher energy density (capacity/weight) than Li-Ion cells.
LiPo cells can be charged and discharged at significantly higher rates than Li-Ion cells.
The bottom line is any small consumer electronics battery pack which is flat and square and is marked as 3.7V (or a multiple of that number for multi-cell series-wired packs) is a LiPo pack regardless of what it says on the pack or in the literature.

I have owned both batteries and I'm quite familiar with the bug OP is referring to. I can say unequivocally this battery has the same issues the 3500mah Seidio battery does. If you charge this battery, while the phone is on, to max and then unplug, you will watch your charge drop from full to in the 60s in the first hour or two. The drain then tapers off significantly at that point.
I haven't really had an opportunity to put this one through it's paces yet and it may stabilize over time. I'm thinking that this new one might provide the same amount of battery life as the Seidio 3500mah one due to this bug.
EDIT: See my post on the following page. The battery/system seems to have calibrated itself.
You mean to tell me that this battery was a waste of money for me? If so, let me know. It will go back tomorrow
Strange, I don't have this issue at all and I've had the battery for almost a week. It tends to drain quickly to 95% then level out.

My second charge drained to about 60% just like the first. I just pulled it off the charger for the third time early this morning and I am not noticing the drain anymore. I'm thinking it must have calibrated itself.
I've been off the charger for 1 hour 50 mins and I still have 93% remaining!
This is much more like the stock battery. If it continues to act this way, this battery beats the Seidio one by a mile. It's been a couple months since I've used the EVO. Has something been changed in the CyanogenMod Supersonic kernel to support extended batteries?
Shouldn't it be draining slower than stock battery?
I ahve the Seidio battery and I have never seen the battery drop to 60 percent or anything else like what people are saying. I am on CM 6 RC1 but even with any of the other dozen ROMs I have never had an issue. If my battery dropped to 60 percent a short time after unplugging it I would have sent it back the same day.
I charged my battery from 5% to full last night via usb charge. I pulled it this morning at 7:00 and it dropped to 93% quick mainly because it was on the charger well after it had reached 100%. Since 7 am Its dropped as it should. Im currently at 71% 8 1/2 hours later. So I wouldnt say all of these batteries have the 3500 seidio issue. What rom is everyone whos having the issue running?
They may have fixed something in the kernel recently to avoid this. Look up the old threads about the 3500mah battery. The battery calibration issues were universal.

The EVO stops charging at 100% and will not charge until it drains back to about 90%. The phone will continue to show "full" until you pull the plug. It will then show the true charge level.

Thanks for clearing that up. I didn't read your previous post, I guess
So do you guys suggest to get this instead of the Seidio ?
Someone take a logcat dump and look at the battery parameters of charging/not charging and you'll know if they've fixed the issue or not.
The meter will self adjust to the 1500Mah based on voltage and you think you'll get a full charge but you won't. Slapping it into an external battery charger after "fully" charging it thru the evo will open your eyes to the issue.
Here's hoping, now there's a sprint official "OEM" class extended battery that they'll get HTC to compile in additional battery drivers other than just the 1500mah one it shipped with.
Sorry folks, if you can't charge it externally, you're not going to get the FULL capability of the battery. There are ways to tricking it into taking more. Charge it fully with phone on, unplug, power it off, charge some more, unplug power on, charge more, etc.
This will continue to add just a little bit more to help bring it up, but you'll never get it full unless you can charge externally or HTC adds devices.
You can pull the source code yourself and confirm this info. You can also confirm the issue still exists with an external charger.
Hi,
I've just purchased a couple of cheap batteries off ebay and just wondered what was the best way of using them and charging them?
I've just recently calibrated the battery on the Z the other day (and now been getting upto 22 hours on a single charge! Yay!) and wondered do I need to do the same for the batteries I just bought as they come with their own charger.
I just want to get the best out of the phone and batteries so wanted to know what's the best thing to do.
Thanks in advance,
Jason
I would run them flat (keep phone on until it dies, turn it back on, let it die, turn it on, let it die, turn it on...... until it boots no more) before charging fully/overnight.
Batteries aren't calibrated, the battery meter on the phone is calibrated (basically, so the volt meter on the phone knows what voltages correspond to "full" battery and "empty"). Li ion batteries don't need to be conditioned like the old NiCad type. Really, you don't need to do anything. Li ion batteries should be stored with about 40% charge according to the link below. They should have shipped with some charge, and hold the charge pretty well. Just check them once in a while if stored for a long time.

No! Do not run the batteries until empty. Running a Li ion battery empty can possibly cause it to no longer take a charge. Try not to discharge below 20%. See the link below. The proper way to calibrate the battery meter is charge to full, drain to about 20%, repeat a couple times.
http://batteryuniversity.com/learn/article/do_and_dont_battery_table
And as I've already mentioned in my previous reply, charge/drain cycles on the battery does nothing does nothing to the battery itself. Li ion batteries don't need to be (and can't be) conditioned. Charge/drain cycles only calibrate the battery meter on the phone (possibly incorrectly, if you are just going to then store that battery). So you are just wasting your time.
Also, you shouldn't store the batteries fully charged.

Really?....
Links added to 'to do' list for later. Thank you pal. I really should research before taking peoples word as gospel.
Nice one.
What I've done is counter to what people always say about Lithium Ion batteries but I've had good success so I figured I'd share.
I have two batteries, one always lives in the phone and the other lives in an external charger (these can be had for as little as $5 on eBay).
Every morning I look at the phone and if the charge is <50% I pop the other battery off the charger and put it in my pocket. When the phones battery dies (may not be that day) I just swap the battery and when I get home I put the dead one on the external charger.
Periodically if I'm not in a hurry, I will even go so far as to power the phone on in recovery mode after the battery has died, it will run for a bit longer in recovery (sometimes as long as an hour) sucking a little bit more juice out of it.
I routinely get more than 2 days out of a battery charge.
I don't doubt that my method reduces the overall lifespan of my batteries but charge time is more important to me than battery lifetime and I end up picking up a new battery every 6 months ago and taking my oldest one out of service.

No problem. I used to think the same, about draining the battery until the phone died, then charging to full, to calibrate the battery meter. Until Jackos over in the Rhodium forum informed me otherwise. I've also read pretty occasional posts over there (and likely other phones) by various users that discharged their battery too low, and then couldn't start their phones or charge the battery. Every phone is different, and I think a user on here said the Vision has better safety measures to prevent this. But best to play it safe. There is really no benefit to intentionally draining your battery to 0% versus 20%. Your battery meter will still be plenty accurate enough.
Ah ok thanks guys a lot of useful info here.
So to sum up:
- I can charge the batteries normally on the phone without need for calibrating either phone or battery.
And one more question:
- Are there adverse affects from charging the official battery or ebay batteries on the external charger?
Loving the Desire Z at the moment, I think I'll have one spare battery on me when at work or commuting on public transport and one in the car.
Thanks again!

They both charge fine either on the external charger or in the phone but in general I've had better performance with OEM batteries than with the generics, I suspect that there is a wide range or quality among generic batteries where the OEMs are more consistent.
Right now I have one OEM and one Generic, despite the Generic having a higher MAh rating and being newer in general I get more time on a charge off the OEM battery.
You can check eBay for a good deal on OEM batteries, just be sure to read the item description carefully to make sure you are getting a real OEM battery as opposed to an "OEM-type".

If you are going to be swapping batteries frequently, then I would say that there is no point in calibrating the battery meter on the phone. Its never going to be completely correct if you keep swapping the battery. If you are going to use one battery for a long time, I'd say calibrate the battery meter. There is no such thing as calibrating the battery, so obviously no on that.

I'm not sure on this, so maybe others have a better answer. But I'd say as long as the voltage is the same, it wouldn't matter if you used the phone or an external charger to charge the batteries.
From what I've read, Li ion batteries have safety circuitry to prevent over-charge, so you don't need to worry about the charger having that.
I'm ordering a spare battery; what is the best way to give it it's first charge / how should I condition it?
I don't think a lithium ion battery needs to be "conditioned" since it does not have the "memory" effect. It's usually the battery stats on the phone that can mess up the reading.
I would probably just make sure it is fully charged when switching them to be more accurate. But, I'm no expert...

Thanks for the reply.
I'm fairly sure I'd read somewhere that it should be fully charged before turning on the phone for the first time & after that do a couple full cycles (full-empty-full) etc..?
Yes, a full charge before using is recommended (I've also heard to let it sit on the charger for a couple more hours after it is charged helps) and maybe a few full "cycles" after that. But, like I said, I'm no expert and I, personally, have had no issues with my battery

True, it's not for the battery but for the phone stats. Lithium ion batteries are fully conditioned at the factory before being sent out. It's the last step in the actual cell manufacturing process.
Yes, I work for a lithium ion battery manufacturer. We make larger cells (not the tiny ones in a phone battery) but I have contacts and friends that work for other manufacturers that do make the little ones and they're basically all the same.
i ordered too 1800mah batteries cause i couldnt find any 1950s...they both arrived dead i waited 30 mins to charge and turn the phone on, and the other one is extremely dead it shows charging for a few minutes and then the red light turns off
so far the one i charged to 100% isnt working how i would have liked it dropped to 50% within a few hours and i charged it to 100 again and it dropped to 80 very quickly im gonna let it die tonight hopefully i get them to work good
Sorry about your bad experience.
Don't know what you purchased or the vendor, but I purchased a 3200 mAh batt from Siedio and am quite happy with it. I've been using it for over a month and get heavy use of my Atrix. High quality batteries are not cheap. Don't get the $20 dollar specials. (I have no financial interest in Siedio, I'm sure there are other vendors with quality batteries).
Battery calibration has been a challenge but I think I have a solution. I'll know in a few days as I'm presently recalibrating. It would have been so much easier if Moto had added a 5 cent current sensor to the phone.
I wouldn't worry too much about conditioning it. Just use it like you regularly would any other battery. Most horrible battery life comes from the way Android handles the battery stats. In my experience, most Li-ion batteries seem to really get their most effective use cycles after about a week or 2 of consistent usage. If you're experiencing some really drastic battery drops though, that's when it may be time to recalibrate the battery stats or start questioning the rom/radio/kernel that you're using.

Yep. However, unless you're impatient, charging it to full shouldn't do you any harm
For Lithium ion batteries, I've always put them immediately on the charger, let them go to 100%. Then unplug and let it completely die (that is, let it get so low the phone turns itself off) without pluging in. Then charge back to 100%. After that, use as normal. Doing this has gotten me long battery life, both short and long term compared to others I know who dont do that.
When I bought my phone the Bell representative said to fully charge then discharge the battery. I thought that you aren't supposed to do this though because Li-Ion batteries lose some of their maximum life when you do that. Only Ni-Cad batteries needed conditioning like that.
I could be wrong though. Would be nice to know proper procedure for this kind of thing

You're right, lithium ion batteries should not be fully discharged but it does help the first time to get the battery reading accurate. After that just charge whenever. It only really becomes a problem if you let it go dead too often.

+1. There's two reasons store reps tell you to discharge and charge the battery at least one complete cycle before using the phone. The first is that they're stuck in the past and think li-ion tech is the same as NiMH. The second and more sound reason is that it helps to set the battery statistics. If you're one of those people who loves to mod their phones right when they open the box, you could theoretically bypass this step by rooting and charging to 100%, and then just doing a manual battery recalibration by wiping the battery stats.

Yeah - if these are the Chinese jobs that came with the charger on Ebay, I got them too. They drop REALLY fast down to 5%, then I get at least another 24 hours out of them. It's crazy. I have tried to recalibrate by removing battery stats, but these haven't gotten any more accurate in several full charge / discharge cycles.
I suppose I will use them as spares, and just understand that the meter is not accurate on them. I still get a minimum two days with these cells. Will see how long they last. With batteries, you do get what you pay for.
I purchased my 5t about 4 weeks ago and the stats in AccuBattery are now showing my capacity at 2930 mah and the health at 89%. If accurate, these are somewhat concerning considering how new the phone is. Anyone else seeing similar stats? I ran AccuBattery on my Nexus 6p and it always seems pretty accurate.
That's the same capacity I get on my phone with AccuBattery. Other people on the OnePlus forums also had the same results so I think that it is probably normal.
I don't trust that application any more (even if I bought it 2 days ago). So i purchased my phone 4 days ago and after the second charge it says 89%.... Many battery applications are useless on the Play Store.
It is a little wonky on certain phones sometimes. Have you done several charge and discharge cycles? I know it definitely won't be too accurate until you run it a few times. Since you said you used it on your 6P though, I'm guessing you know this already. As long as battery life is still good, I guess I wouldn't worry too much.
I run Accubattery on my mine, it says 92% after a couple of weeks. Battery lasts for a full day of heavy use, and then some.
I also ran it on my 2 year old Moto X Style, and it said 51% - and I felt it was telling the truth, since I got about 2hrs SOT from it if i was lucky!
Same for me, showing about ~3000 mAh from the beginning.
It's also showing ~107% on a Nokia 3 of a friend of mine, so I guess you just can't trust the app on that perspective.
lol, guys
ok now, several factors to consider before you jump to conclusions (ive been using accubattery for several months now with great results):
1) your sample size is waaay too small. every scientist/engineer/mathematician, etc out there will tell you that u cant jump to a conclusion based on just two samples. give it some time, use the app regularly for several weeks and only THEN can you make assumptions about the accuracy of the collected data.
2) ive noticed that the final capacity reading is more accurate, the closer a charge cycle is to 100%. which makes sense if you think about current quick charging technologies: they provide high amperage at steady voltage at first up to like 75-85%, then they switch more and more to trickle charge with low amperage. advantages: fill up the battery quickly, but without putting too much wear onto it.
thus: if you just do a quick charge cycle, say from 30-50% then the slope steepness is way higher, thus the calculated capacity will differ. so there is a dilemma: either do large charging cycles with higher wear on the battery, but more accurate capacity data in the end, or do smaller charging cycles with inaccurate data but less wear on the battery.
3) when charging to 100%, dont unplug the phone when it reads 100%! rather check the current charging amperage in accubattery. only when that drops to zero (or -1 mA in my case) is the battery fully charged and ull get a more accurate capacity reading than when stopping the charge when 100% is reached. if you unplug it too early, the capacity calculation will be on the low side
hope this helps!
cheers

Yup, am scientist, can confirm
Same thing happened to me, even after using AccuBattery for a couple of weeks (and thus collecting more than a couple of samples, both Dash charge and "normal") it still showed 89% battery health at around 2940 mAh. Got my phone one month ago.
I don't think there's any problem with the battery itself, especially as it's not just me having this problem.
Maybe the battery is 3000mah and they are lying about it ???

I'd say 30% of the times 10 to 100%
40% of the times 30/40 to 100%
And the rest just random stuff: 50 to 100, some top ups here and there
This is not scientific data though, that's just what I recall from the couple of weeks I used AccuBattery. I'll try to find a screenshot but I doubt I have any.
I reinstalled it today and from a single 14 to 80% charge it gave me ~2930 mAh and 89% health. I'm on OOS 5.0.2 stable, will try the app for some time and share my results (more scientific this time)
After several weeks of use, the reading is still constant at 86% ~ 2827mAh. Not sure what to think. As previously mentioned the first 5t I purchased and returned for the 128gb version came in at 89% same as @Explyy. Is it possible I have an inferior battery?
hm, there indeed seems to be a pattern emerging with so many different users reporting identical capacity values at 2900-3000 mAh for their new op 5t. two possibilities: either accubattery cannot properly read out and analyze the 5t's battery charge controller. or the battery capacity is indeed around 2900-3000 mAh instead of the advertized 3300. its normal for battery capacities to be around -100 mAh from the official value, but -300 to -400 would be crazy.
guys, just to be sure: did you leave your phones plugged in until the charging rate in accubattery dropped to 0 mA? as i said before, if you unplug the phone once it shows 100% but still charging, the resulting capacity will be less than the actual one.

Yes, I left the phone plugged until the charging current dropped to 0, as I noticed that when it reaches 100 it's still charging at a few mA
On a related note I charged my battery from 10% to 100%, until the mA rate dropped to 0mA. I had the phone hooked up to a USB power meter during this time. The USB meter only read about 2500mAh charged. So since I only charged 90% of the battery I figured it should be around 90% the capacity of the battery, which is 2,970mAh. If I assume the battery is 3000mAh then a 90% charge would be around 2700mAh, closer to my reading. I'm going to run some more charge cycles and see if I get the same results.
Edit: forgot to say that I used a standard 2amp charger, not the dash charger that came with the phone.

Did you use the dash adapter or just a regular one?

and still no difference in the calculated capacity in that particular cycle?

As far as I remember no, always reading ~2950mAh

Someone who's having accubattery report ~3000 mah should download AIDA64 and look and see what it reports the battery size to be......
