[Q] Is USB tethering when it's fully charged bad? - EVO 4G Q&A, Help & Troubleshooting

Is it bad to USB tether when the battery is already at 100%?

Why would it be?

if you mean is it bad to leave the phone charging via usb when it's already fully charged.....no.....it's not "bad" as in it won't hurt the phone.
consequently, you could condition the battery to not hold as much of a charge if you never fully deplete the battery's charge or always keep it plugged in. It's always good to run your battery out as much as you can, and then fully charge it as much as you can.
hope that answers your question

lol....poeple on this forum are ruthless...funny though.

Wasn't being "ruthless"...just genuinely curious what he's thinking.
And you're not supposed to run these batteries dead to "condition" them. They don't have a charge memory.

Back in the olden days not so long ago, the rechargeable batteries were made from
liuthium ion, and had what were often refereed to as "memory". So running them "flat",
then charging them, produced a longer lasting battery. Today however, they are
frequently made from nickel metal hydride, which does not have those "memory"
properties, that the lithium ion batteries possessed. It is worth noting tho that many
of the ROMs available - including HTC sense, have "training" algo's that attempt to manage
the phones running resources in such a way, as to make the batteries seem to last longer.
But really, they just try to minimize the draw on the battery.

Nononono.. You should really brush up on your battery history, lithium ion and lithium polymer niether have memory, ni cad, or nickel metal hydride do have memory. Our phones, all cell phone run either lipo or lithium ion, I think they are lipo, I know this because I run rc cars that have a 250 dollar esc that you don't want to burn up, so I know a bit about these batteries.. But you are right on the roms they are becoming a bit better on batteries, but if your over clocking don't count on to much, but you are also right you won't hurt these to leave them on the charger or to run till dead.

Yes - that was kind of obvious. I think the question was WHY you do not want to "charge the battery when p3600 is connected with pc".
If you have a reason that others have not thought of, others might decide to do the same. Seeing as the USB is the only way to charge the phone - I'm guessing the only way to do this is modify the cable you use to connect to your PC. But then you'd NEVER be able to charge using this keyboard.

its good to wait half hour b4 any phisical exercise because the blood is naturally redirected to your stomach after esting to help digesting, exercising screws that up...
Watching TV is harmful in many ways, eyesight, radiation, hormones, day/night cycle, Can even trigger epilepsy...Especially using old TV sets.
Reading in poor light conditions can damage your eyesight if you do it often enough, it is possible to overwork any organ... Plus you get related problems like bad posture and back problems from subconscious compensating...

sorry for my english. i hope you understand me ok
I agree with Lithium ion batteries do NOT have memory...
... but i'd like to avoid charging battery when i connect Trinity to Pc because ALL batteries have a limited number of charge cycles.
continously charging make battery cells at the top lost a lot of charge cycles while the bottom cells no.
When battery cells finish the number of life-cycles, they are no more usefull decreasing the total capacity of battery.

So I bought the Seidio 3500mAh...

And it doesn't seem to charge pat 70%. I'll leave it on the charger until it is at 100% (not 90% like some people have issues with), and then when I take it off, within 2-3 hours I am down to anywhere from 72-68%. This isn't with heavy use, for example this morning it has been off for 2 hours, it is at 75% and I did nothing with it except read one email.
Just testing things out, I charged it while the phone was off, and it seemed to discharge slower.
Is this a common thing with these batteries or is mine somehow defective?
Thanks.
Did you recalibrate the battery in your recovery? Charge to full, boot recovery, wipe battery stats, then let it run till it dies.

I did, but I might try that again. It may not have been actually at 100% (I didn't turn it off, because I didn't know about the issue when I calibrated).
All the other threads had the answer but.....
The driver that has the stats for the 3500mah battery isn't there.
They only included the driver with stats for 1500mah.
If you want to fully charge the battery, you have to do it externally. Even with phone powered off, it may not fully do it.

The evo can't charge the seidio or any non-htc battery properly. Get an external charger and watch your battery life increase with every charge. I don't even wipe battery stats anymore.

That would make sense... I might ditch it then, if I can't reliably charge it 100% because the battery door is pretty hard to remove compared to the stock one and I don't want to end up breaking it one day.
Is that something that would be in the ROM? I'm just wondering if it's worth holding out hope for someone to write a driver for it in CM6 or something.
Yeah I just let it charge until it turned green, turned it off and let it charge until green again (another half hour or so), unplugged it and did it again and it is now at 89% after literally just wiping the battery stats and booting up.
Maybe I'm just being too neurotic about it. It lasts 2 days, I guess I should be happy, but with the stock battery I got 30-36 hours using CM6 and Snap, so I was hoping for more than that.
Been having similar issues did a full wipe the last Rom I loaded and now two hours after unplugged I'm still at 100% so who knows.

It's hard to say if it's in the rom because the evo itself will not charge any non-htc battery correctly even when it is turned off. It seems there are both hardware and software controls to ensure nothing but the evo battery gets charged correctly.
Here is what I did about the battery door http://forum.xda-developers.com/showthread.php?t=786101
The fact that this battery has been out for so long, so many people have it, and HTC knows about this flaw and hasnt done anything about it is absolutely pitiful and HTC should be ashamed of themselves.
As everyone has said, the only way to get a proper 100 charge is in an external charger. The closest way to to do it in the phone is to leave the phone charging overnight, unplug it when you wake up, and plug it in about 5 minutes later to top it off. Youll get close but it still wont be true 100.
Either way, the only way to properly charge any extended battery for the evo is in a wall charger.
dang i should have canceled my order. Seidio's stupid cancellation policy made me not do it. "cancellations after 2 hrs incur a fee" Now im going to have a Evo with a pot belly and a empty stomach. BS

Yeah it seems like I guess it's mostly HTC's fault in this manner. I'm back on the stock battery for now. I might just keep the extended battery at ~60 (apparently the best way to store Lithium Ion) and when I plan on heading out for a weekend trip or something like that, I'll charge the battery up and put that in my phone.
For everyday use, having to remove the battery to charge it sucks.
What would be ideal is if HTC allowed you to key in the MAH of the battery you have installed in your phone or something along those lines to ensure the battery gets charged correctly . I know its a long stretch but hey I can dream ROFL . This charging bug has been the one major thing preventing me from getting an extended battery . I have toyed with the idea of getting a chinese one for cheap just to play around with and so forth but not to drop the cash Seidio wants for theirs . HTC needs to address the charging issue anyways , most users that use a wall charger for their stock batteries have reported improved battery life . Its sad when a cheap wall charger from china out performs charging a battery better than a 600 dollar phone is able to .
I dug thru the code for the battery driver. There seems to be 3-4 different driver sets, but all are 1500mah or less.
It's been many, many years since I programmed, but the structure has an array of temps, max, min MAH, charge rate, and quite a few other specifics relating to battery.
I'm not sure the logic between the charge circuit, the battery and how it knows which battery is inserted, but some of this info is parsed into the logs while it's charging.
A decent programmer could probably code and recompile this into the OS. That programmer isn't ME. I switched to engineering and networking too long ago to remember enough not to blow stuff up.
This is the one thing keeping me from purchasing a hicap battery. Good to hear that it is software related though. Maybe if they got a pool going some enterprising dev will take a whack at it. Disclaimers work

im wondering if cyanogen and co can work their magic
I'm quite sure they and many others could, but not everyone has the Seidio battery, compared to the numbers of EVO users.
It's probably not worth their time and effort to bother.
What WOULD be nice is if the Seidio folks had programmers instead of just sales folks and could code their own patch for their own products.
I won't be holding my breath tho for any solution. it's ok for me, I have the external charger from my TP2 days. Plus spare batteries as well and don't mind switching when needed. I knew of the issue and was prepared for it before purchasing.

Yeah I wasn't so much prepared for it. I heard a few things about it, but nothing solid for sure, I should have done some more research. All the reviews on websites were glowing, but I usually take that with a grain of salt.
Too bad even if Seidio had programmers, I'm on CM6 so that wouldn't help me too much haha. On my stock battery I'm getting around 24-28 hours which is plenty fine I guess. Not looking forward to when the battery starts losing its maximum charge, though.
So i don't have an external charger...but i followed the instructions via seidio...
heres what i got:
Rom: CM6 Final Stable
SetCPU: 245/1152 Conservative (Freq Step = 10)
Took phone off charger (from phone) aat 5:30AM
will post back later today with results (hopefully good)

Battery Life Doesn't Matter

(Personal opinion here, of course.)
I don't care about battery life. The battery on the Galaxy Nexus is removable. When my phone is dead, I swap out my battery for another one. Two batteries gets me through ANY day, regardless of usage patterns. Batteries are small and fit in men's and women's pockets easily. They fit in glove boxes, desk drawers, etc. They're portable, lightweight, compact, etc. You can take them almost anywhere.
I purchased the Samsung battery charger kit and haven't looked back. Instead of charging my phone and feeling tethered to my charger all day, I use my phone however I want and swap batteries in/out as I need to, and I only charge my phone overnight while sleeping now. The rest of the time, I only charge my batteries through the charging kit.
All these threads on battery calibration, battery life, etc. just seem unwarranted to me. I'm used to toting a charger around with me, so now I just bring my battery kit (usually it sits in my car, not needed) and if my battery dies, I swap in a fresh one and charge the spare with the kit. This way, I can have my phone on me all the time without worry. If I have no nearby electric outlet I can still take along the extra battery and charge both batteries later. I actually have 3 batteries, if I need them (I can't imagine ever using all 3 in a day).
I don't even use the extended battery. Why fatten up my phone, even if only by a little, if I don't need to do so?
This is food for thought, that's all. Does anyone else just use spare batteries and no longer worry (or even obsess, as I used to do with my Thunderbolt) over squeezing out every drop of battery life? To me, life is easier and better this way.
There's a name for the feeling of not being tethered to your charger all day. I call it freedom. It's awesome.

I see where you are coming from.. What do you think of the battery cover? Is it difficult to work with when swapping batteries and will it last with such frequent use? How do you make sure that your spare battery is always ready (I guess you must be in the habit of always putting it on a charger)?
The battery cover is easy to remove. I ordered two spares when I ordered my battery kit (door covers are only $3 each) in case they wear out over time, which I doubt will happen. Many days I don't even swap batteries, as my phone typically lasts 10-12 hours on the regular battery anyway. I do charge my phone in the car (why not? my phone would just sit there otherwise) which is ~30-45 minutes a day, enough for an extra 20% charge mid-day which helps my battery hit the 10+ hour mark. And if it doesn't, I just swap for a new battery.
The spare is always ready because I always keep it in the charger kit so I can grab it when I'm in need. The kit has a light which turns green when the spare battery is charged to 100%. The light is red otherwise. It's quite handy.
At night I plug in both my phone and the charger kit using the Y cable charger that comes with the kit (allows 2 devices to charge simultaneously on one charger). In the morning, I have my phone and spare, both ready to go.
May I also say, I've impressed a few of my iPhone-using friends with my spare charger kit. They always say "I wish I could do that, but I don't have a removable battery." I lol every time (silently to myself...)

I completely agree. That and who is really not near a charger ever all day? Maybe a few but hey that's what changeable batteries is for.
I see nothing wrong with improving what we have with calibration and optimization though...
Lol sounds like you are super jaded from using a thunderbolt.
IMHO your logic is flawed. Why not get good battery life on one or two batteries rather than mediocre battery life on two batteries.
You shouldn't have to carry around two batts just to get usability out of our device. Two batteries is for when you demand extra from your device.
Like when I went to New York I carried two batteries for my BB9700. Not because it was a battery hog but because I was GPSing and texting all day and didn't want to be stranded with a dead battery. I ended up using both batteries several times skipping charging both of them one night.

edit: I get great battery life on this phone btw. I love it and am very happy with its performance.
I do the same thing. Have the extra battery with wall charger and just throw the spare in my pocket if I go anywhere. Like the OP stated I would much rather swap out the battery (if/when needed) and be able to use my phone like I want than worry about trying to conserve it all day.
I haven't had any problems with the battery cover and even if it did I can buy a new one from VZW for $3.25 with my discount ($4.99 retail) so it is a nonissue.
I honestly don't know why so few people do this. And I very rarely even end up using the spare battery, I just like knowing I have it if needed.

Agreed. I read that stuff to be informed, but no longer out of a crazy desire to extend my battery life because I can't live without doing otherwise. It's a nice change.
Again, I'm not saying anyone else has to or should do this. But it makes so much sense to me, and I like to share what works for me to help others who are looking for other options regarding battery life.

I'm a realistic type of guy. What I want from my phone and what I get from my phone are two different things. To believe they are the same is literally delusional, by definition. To complain about X Y or Z company not providing me with what I want is also a bit irrational if I know that, given today's technology's limitations, what I want might be asking a bit too much. We must work with what we have. I have spare batteries. I use them, liberally if I need to, and I don't mind doing so.
I don't expect a 4G phone to last all day while I play WWF, browse the web, text constantly, check and compose emails, take photos, transfer data, and make phone calls. To get 3-4 hours of screen on time on one battery is great (to me).
I think carrying an extra battery is being more responsible on my end for my own admitted usage of the phone, rather than complaining that the battery life "sucks" or hacking my phone to get an extra 20% battery life (although I'm not against this at all - it's just more work overall). Instead of blaming Verizon, Google, and/or Samsung, I'm taking ownership of the fact that I use my phone quite a lot, and I'm fine with carrying an extra battery or two. Instead of blaming others for the battery life of my own phone, I take responsibility for it and I provide my own solution. If anything, I'm speaking of personal responsibility. And in said responsibility I've found freedom from the dreaded phone charger. Again, it's a nice freedom to have.

I agree completely with the OP. A second OEM battery and quality wall dock charger are my second accessory purchase with any of my smart phones. The first being a good case.
Having a 2nd or 3rd (or 4th!) battery and/or a charger around shouldn't be a requirement for using your device throughout the day. Sure if you use your phone hard then you're going to be used to having a charger nearby, but it shouldn't be a req if you're a normal user.
I don't think its unreasonable to expect a normal (12 hours) days use out of a device. FWIW most people are getting that (especially GSM users), and I don't think the battery issues are as widespread as people seem to think. There are "omg batterylife" threads in every new device forum.

I often go a full day without seeing a charger. Sure I could carry one around and hunt for outlets throughout the day, but I don't think that should be a concern. Just want the phone to be reliable.
For what it's worth, I bought an external charger a couple phones back. Just plug in via USB to the phone if it's running low. Really useful when I'm on the train, for example, and I tether wifi for my Xoom. Gets me through the day in a pinch and I don't have to buy a new one with every phone (though I might buy a larger one now given the Galaxy Nexus' bigger battery).
Also, I usually plug the phone in while at my desk and always charge overnight. But I use the hell out of my phone

I have to agree with Martonikaj I'm afraid. Its a phone, just because you CAN swap out the batteries doesn't mean you should HAVE to to get reasonable usage life.

I disagree with the OP for having 2nd, 3rd batteries in order to use it properly based on user usage pattern.
First, define your usage pattern then try to optimize the battery to support that.
My usage pattern requires to have at least 3 and a half our screen time, and charge the phone once every two days, before I went to sleep (or during the night).
And this phone battery can do that without any problem ...
So, I don't need second battery ... and I am ordering the 2000mAH extended battery for GSM model. Having extra 250mAH is nice, it's a bonus for additional 30 minutes screen time! ... while still having the same look and thin device profile
Hey guys can someone recommend a good place to buy a second battery and charger if needed? Is it worth getting the extended battery and do I need to buy a different back cover if I purchase one? I am in Australia so was thinking eBay might be my best bet? Cheers
I do the same as the OP. I have three batteries that I rotate through. The OEM Samsung battery that came with the phone and two 1900mah batteries that I bought from eBay (which aren't too bad by the way) . I don't ever have to plug in my phone anymore because most of the time I have two fully charged batteries ready to go. I get on average between 12-15 hours on a single charge as it is with pretty good use, so I'm not worried about my phone dying, its just more convenient.

I always had this question in my head and i think its time to ask. All android phones i had does this and i wanna know if this does harm in somehow the battery.
When i plug the phone to the PC to transfer some files it recharges the battery too, sometimes depending how big are they, the phone stays connected for longer. I want to know if it harms the battery doing this small, medium charges while transfering files.
Doesn't harm the new batteries.

Ok, thanks.
... what Flo95 said.
More specifically, lithium-ion batteries don't develop the 'charge memory' older battery technologies like NiCad do if not allowed to fully run down before a charge.

Older batteries suffered from "memory effect", meaning that if you charged them before they were empty and until they were any less than full, soon enough their capacity would deteriorate.
New batteries don't have that problem. You can charge them any time you want for as long as you want. In fact, it's advisable to not let them discharge completely and charge them often.

Thanks for explaining it for me
It seems a bit ironic, previously we had to be aware from charging at any time and it was stronly recommended to charge only when battery is completely dead.
While these days it's better if we not let the battery completely discharged

[Q] Battery - should I charge straight away, or let it run down first?

I'm not up-to-date on battery etiquette, so thought I would check with you chaps. I should be picking my One X up from Carphone Warehouse tomorrow or Wed, but wanted to know whether it was considered better to charge immediately, or to use the battery until the phone dies, then charge fully, or some other third option. Want to make sure I get the best out of the battery, obviously.
Thanks!

What you really want to do is condition your battery. You don't need to do it immediately but in the first week or so of having the phone. By conditioning, I mean... Charging it until it's full, then using it until its fully discharged, then charging it again. Repeat this cycle ("fully discharged when charging") for 3 to 4 times... after that, you'll notice that your battery lasts longer than usual. It's what I've done with all my phones, seemed to work pretty good.

But were you using Lithium-Ion batteries? From what I have heard, completely depleting the power of the battery actually damages its health.

A lot of the time android will shut down just before your battery is 100% empty, you will find if you try to turn your phone on after its shut down it will still boot and run for 15 - 30 mins, depending on battery age and condition ofcorse. And if you keep on turning on the phone when its battery is very low/empty you will then start to damage it.

Some one posted this website before:

It also has a nice table about how to look after your battery:

How to Prime Batteries
...Rechargeable batteries may not deliver their full rated capacity when new and will require formatting. While this applies to most battery systems, manufacturers of lithium-ion batteries disagree. They say that Li-ion is ready at birth and does not need priming. Although this may be true, users have reported some capacity gains by cycling these batteries after long storage....

Charging the battery
Before you turn on and start using HTC One X, it is recommended that you charge the battery.
Only the power adapter and USB Cable provided in the box must be used to charge the battery.

However there seems to be a common agreement that over the first week / two weeks of usage the battery will improve...
Last quote from MaDaCo review comments from Paul when asked how does he condition his battery:
I don't really condition it tbh, I just find it takes a few charges to get 'up to speed'.

Conditioning the battery was needed with old style batteries.. new Li-xxx batteries don't need one.. and what does an extra 30mins actually mean to you ...
now you can buy original replacement batteries for 20-30$, so if it loses it's capacity after some time you can easily buy new one...

I'd use the battery as soon as you get it until completely drained.
Then perform a full battery charge without use, its best to do this to ensure a full 0%-100% charge.
