Battery test with case holder - 30% loss
 

ok i have been testing my battery with my magnetic case holder.

I have OEM HTC case. i did use the tweakt to slidewake to zero.

here the results after 8 days of testing every night i 100% charge my battery. if i leave the phone in the case with the battery facing the magnetic clip it will drain 30% of battery life after 8 hours.

if you place it on the table and not in the case battery life only lose 5% - 10%.

My conclusion is the magnetic field is attracting the battery to drain quicker.

If you flip the phone in the case then there is no battery loss..

So bottom line people with magnetic case either flip your phone so the battery door is not facing the magnet, or at night time remove the phone from the case..

i hope this helps other who notice battery loss overnight or during the day if your phone is using a case with magnetic holder..

thanks for posting your findings

Re: Battery test with case holder - 30% loss
 

anytime every little info helps if you want to maximize your HTC TP2.

i can't put the phone in my pocket it just feel to bulky. i have always used a case. so when i go out all day and night hate to waiste 30% battery life or more just cause the magnetic clip is pulling the power.

enjoy i hope it helps other using magnetic case.

I've also notice drain with my magnet holder. I think I'm going to return it and just live with my ghost armor. The thing is I wear scrubs and those lack pockets :(

Re: Battery test with case holder - 30% loss
 

It has been a real battle but I finally found a leather clip holster at WalMart without a flap and thus no magnets. Sucks because I have an extensive collection of leather holster cases in a shoebox in my closet but the majority of them are BlackBerry cases and they ALL have magnets. I cant pocket the device either , its just not safe.

I have found that I cannot using any magnets with my TP2 or it causes me grief...

Re: Battery test with case holder - 30% loss
 

Are you guys sure it's the magnet in the case? I find that when I'm at work and I leave my phone on my desk, I can get 2 full days(~48 hours) out of a single charge, whereas if I keep it in my pocket for a few hours, I'll have to charge that night...

Re: Battery test with case holder - 30% loss
 

Im wondering also if the increased battery drain is due to

A: if its in the case its probably on the move meaning its searching for towers/switching towers more often.
B: if its not on the move its possible that the case is hampering the signal enough to cause the phone to have to search for a better tower?

Do you have another leather case without a magnet that you could try?

Edit: you did mention that flipping the phone around seemed to solve the problem and I dont see how doing this would change the result if it were either of the reasons I posted so....ignore this post :-p

Re: Battery test with case holder - 30% loss
 

lol I'd like to know how a static magnetic field effects battery life?

Re: Battery test with case holder - 30% loss
 

I've seen a video someplace on this subject, and yes, SOME cases with magnets will cause the battery to drain. The discussion is in one of the many different forums, but I also think that the video is on UTube. The reason being that there are a couple of small magnets inside the TP2 that turn the backlight on when the keyboard is opened..which will drain the battery.

You can test your case, by placing the phone on a desk, face up and wave your magnet over the face close to the surface. If the backlight doesn't come on, then your case is probably OK.

The video proves this fact.

I can see the case magnet tripping the screen sensor. I just don't think a magnet around a battery will somehow cause an increase in current and drain on battery.

Re: Battery test with case holder - 30% loss
 

Here's a video that proves the magnetic case will cause the battery to drain. It may not be by the battery, but it does turn the TP2 on

Re: Battery test with case holder - 30% loss
 

Well if the magnet is constantly telling the display to turn on and that the keyboard is open and shut repeatedly while in the case that is going to drain the battery obviously...

Re: Battery test with case holder - 30% loss
 

Quite right. I was thinking the slidetowake tweak the OP did would of eliminated the screen turning on though. So I was thinking, if the screen didn't come on, then there's no way a magnet could drain a battery. But if his screen does come on, then well, yea, waste of battery.

Re: Battery test with case holder - 30% loss
 

also i noticed that if you are in an area with spotty reception the screen will come on automatically if it goes from no reception to having bars. its annoying to leave it on the table and see the screen turn on every couple of minutes with no activity.

Re: Battery test with case holder - 30% loss
 

but wouldn't putting the phone LCD out toward the magnet damage it after a while like a magnet on a TV screen? I'm not trying to burst anyone's bubble here, nor do I want to test it and find out lol.

Re: Battery test with case holder - 30% loss
 

If you bypass the magnetic sensor there (should be) no way it can drain the battery. But I have been wrong in the past.

Re: Battery test with case holder - 30% loss
 

finnally thank you!

Re: Battery test with case holder - 30% loss
 

I have tried it both ways and it does nothing to the screen.

Re: Battery test with case holder - 30% loss
 

OK i did a test for 8 consecutive days with battery facing the magnet and battery not facing the magnet.

as you can see i lost 30% battery power all four days.

i lost 5% - 10% battery power when battery was not facing the magnet..

remember i have a OEM HTC original leather case and magnet is not that strong.

i can tell you a PHD confirms there is a direct corolation between magnetic filed and battery...

So you can do what ever you like or disregard my findings....

My TP2 last 1.5 days with average useage with my phone in the case all day and night.

before i was lucky to get it pass the whole day with battery door facing the magnet...

for me it does work i am happy and there is noway i am facing my battery towards the magnet...

Re: Battery test with case holder - 30% loss
 

Just to throw some more conjecture in, I think that my problem may be more a situation of the case being tight on the ON button on the top of the phone pushing the button as I walk. I've taken the phone out of the case and had the "DO you want to turn of your device?" message on the screen which would indicate that my case had held the button down for the requisite amount of time.

Guess if the phone was sitting on my desk in the case I could test it against it not in my case (like talked about above to see) but I still think that there is a problem with the phone turning on because the button gets pushed.

I installed S2U2 and think that with the 10 sec. turn off if the unlock slide isn't done that that has helped (because at max the screen only stays on for 10 sec if the button is the culprit).

My 2 cents adjusted for inflation....

Re: Battery test with case holder - 30% loss
 

i use pockeshield and my phone is a perfect fit the power button is open no interference at all with case...

i am 100% that the magnet is draining the power and yes i already tweaked my phone to "sidewake = zero"

that the first thing i did and still notice battery drainage. it was by luck that one night i had 60% power left the phone on the table went to sleep 8 hours later i still had 60% battery i said hmmm that is when i started experimenting with my case and you know the rest..

Re: Battery test with case holder - 30% loss
 

People really should stop to consider there are many other factors involved , such as if you "lock" the device before holstering OR if you listen to steaming music in the background, both those will break the magnet slide fix thus making it not such a "simple fix".

Even with the slide fix enabled when I remove my TP2 it makes the slide sound , instantly wakes up and is screaming hot and battery is depleted completely within 4 hours. Same phone, new case (no magnet) , same daily routine working in the shop with streaming music for 8 hours or so and this no longer happens and my battery life has increased 2 fold or more.

Re: Battery test with case holder - 30% loss
 

well said i agree with you. we all here to make the most out oour TP2 and the experience good or bad we have..

Re: Battery test with case holder - 30% loss
 

you should pm people if you feel the need to single anyone out.

Re: Battery test with case holder - 30% loss
 

My TP2 doesnt do this, maybe we can compair eachothers cabs and tweeks and figure what might be causing yours, and others, phone to do this. After my "SlideWakeUp tweek" ( [HKEY_LOCAL_MACHINE\Hardware\DeviceMap\Keybd] Create new dword "SlideWakeup" with value of 0 and soft reset. ) my phone absolutely does not respond when passing any kind of magnet across it or sliding the keyboard even after several soft resets. It wil however do it after a hard reset.......;)

ClevelandWheeler is the best!!!

Re: Battery test with case holder - 30% loss
 

That reg tweak works as long as you dont lock your device OR stream music in the background. Try locking your device , then put to sleep and then pass the magnet over it.

Re: Battery test with case holder - 30% loss
 

Your awesome thanks!:-$

Re: Battery test with case holder - 30% loss
 

I use S2U2 all the time but I dont stream music

Re: Battery test with case holder - 30% loss
 

You actually read my mind!:occasion5:

I have not used S2U2 on my TP2 but I did used to use it on my TP. I was using the stock WinMo lock. And I stream music all day everyday at work, its the only thing that keep me sane ( I think )

Re: Battery test with case holder - 30% loss
 

maybe its the stock locker then have you tried not streaming music and seeing if the screen still lights up? Do you want me to post the S2U2 cab? Might work better than stock and it shows the weather. (i have no clue what the stock one has)

Re: Battery test with case holder - 30% loss
 

yes I would like it please.

Re: Battery test with case holder - 30% loss
 

I sent it to you.

Re: Battery test with case holder - 30% loss
 

I would be much obliged. Thank you kind sir.

Re: Battery test with case holder - 30% loss
 

Got it thanks!

Re: Battery test with case holder - 30% loss
 

Here is the S2U2 cab (I didn't make it) let me know if you need anything else. it has a spaceship wallpaper...lol I know...but you can change it.

Re: Battery test with case holder - 30% loss
 

i use pocketshied cause s2u2 use to take a lot of power ...

again my 2 cents my opnion...

Re: Battery test with case holder - 30% loss
 

I haven't really noticed a battery drain but then again I haven't tried any other locker....if you post the cab I wouldn't mind giving your 2 cents a try.

Re: Battery test with case holder - 30% loss
 

Thank you for the cab and thanks for your insight.
