Inaccurate battery of Sansa Clip Plus (+)

something weird with my sansa clip plus, the battery indicator goes empty faster when reach 50% and below…

after 20 minutes from 50%, that player shut of itself,…

is there any bug with Clip Firmware  ?

The battery level icon/indicator is not totally linear. Kinda like the gas gauge in your car. It takes longer to go from full down to half than it does from half to empty.

That’s just the way it is.

wow, okay, thanks for your info, it makes me feel better, because i think there is something worng with my Clip +… :smiley:

but i think, sandisk must fix this problem by issue the next firmware to solve this anomally.

after i rockboxed my clip + , now i can see battery percentage on the top of the screen,

i think it’s more accurate than just a battery icon which is not informative…

but overall, i’m so satisfied with sansa clip + audio quality, great feature and of course in affordable price…

You can also check the battery percentage from within the original firmware too, although it’s more time-consuming to get there. It’s hidden in Settings > System Settings > Info and scrolling to the bottom.

Many people have requested this information be a bit more accessible, but (at least) as yet SanDisk hasn’t deemed it important, or feasible enough to add it in a firmware update.

Once you rockbox, the battery meter is more linear, not to mention the fact that your battery can last longer, sometimes a lot longer, depending on which format your music files are. For example, anyone that uses FLAC files on their player will see the battery life double with rockbox.

yeah, i know about it… i can see battery percentage in system info…

but, too many step to go there,

if sandisk decide to use battery icon, i think the icon must be more linear and accurate like iPod do.

because, for me battery icon is an important info to decide if there is enough power in my device to bring it away…

FLAC is an efficient codec in Rockbox, but it’s lossless format, so in need more memory space…

my music majority are in mp3 format, if i convert to FLAC think it’s decrease the sound quality…

do you know WHAT is the best audio converter to convert audio to FLAC ?

FLAC is a lossless format, so converting anything to it can’t change the quality.  However your files will get huge so theres not much reason to do this.  Just use MP3 or Vorbis if you want lossy, FLAC if you want lossless.

hemm… i want to know when sandisk release the newest firmware for sansa clip + ?

did you know the periodic time when sandisk release the next firmware updates ?

for me this battery issue is important thing.

So does a lot of people. There is no set schedule or firm release date. When they’re done, they’re posted here first.

Approx. every 3 months or so, depending on the severity, complexity and volume of bug fixes that must be corrected. But given the lack of immediate issues with the Clip+, you may notice that the last update was over 6 months ago. That kinda shows the priority level SanDsk has set to it. The Fuze+ is most likely consuming all of their limited development resources at the moment.

Only if you make it one. :stuck_out_tongue:

 

The discharge curves for various batteries can look surprisingly different.  You probably just have a weird one.  Unless its dying early I wouldn’t worry about it, nor expect a firmware update to fix it.

okay… it’s not a must for sandisk to update firmware regualrly, coz it need a resources to fix all the problem…

but for a player under a hundred dollars , it was a great palyer with a great feature…

fuze give a more margin & profit for sandisk, so Fuze+ will be the priority.

hehhe… for u, just charge it when it needs to charge. but for me i have to know about the stuff i bought.

I have the same problem…after 50% the sansa clip+ will last for only about 30-45 minutes before the battery fully discharges.  However, I’ve noticed that it will take a substantial amount of time to drop form the 90-100% range.

I just bought one recently; maybe it’s a new bug or something?

yups… it was a problem of firmware…

so, like i’ve said before… sandisk must aware about this problem and release firmware update…

for now, the feasible solution for this problem is rockbox your CLIP, so you can see more linear battery indicator, especially in percentage view on ‘now playing’ screen.

Well, no need to Rockbox the player, once you know this aspect of the OF battery gauge.  And if you need the precise battery % level, you can check under the Clip+'s Info screen (under Settings/System settings).

the % level says 28% but the gauge says “dead” … and the Clip WONT play at 28%

so, I suppose when the gauge indicates half it is better to charge up??

Sure.

Asides from the increased battery life, anyways…:wink:

General rule of thumb is to keep Li-Ion (/Polymer) battery above about 70% charge if possible, don’t wait until charge drops very low to recharge it.  See

http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries

“The battery prefers a partial rather than a full discharge. Frequent full discharges should be avoided when possible. Instead, charge the battery more often or use a larger battery. There is no concern of memory when applying unscheduled charges.”

The exception is (1) when you cannot avoid deep-discharging because you can’t get to a charger for some reason, and (2) recommended infrequent “battery meter calibration” deep discharge cycles, about once every 30 charge cycles (or month) according to “Battery University” (http://batteryuniversity.com)..)

I always just put the Clip+ on charge after every use, no matter how long it was used. Simple, problem solved.  I’ve never done a deep discharge on it to calibrate the meter, because I don’t need it to run for more than a few hours of non-stop listening so no need for accurate battery meter all the down to zero.
