Why Some Tecno Phones Come With A Free Powerbank

Tech Suplex has a great article on why
Tecno ships a free powerbank with their
phones. Seems like a great marketing tactic
on face value, but apparently it hides a
darker secret

Out of curiosity, I did a quick check
on Tecno’s battery management,
(thanks to everyone twitter that
chipped helped) and guess what?
Tecno doesn’t optimize android OS
for its hardware, at least not well
enough. Two key indicators of how
well optimized a version of android
is for the hardware it is running on
are the battery usage level of the
“Phone Idle” process (battery
expended when your phone is not
in use, but “listening” for activity e.g:
calls/emails etc) and “cell
standby” (which has to do with your
antenna and how power is managed
with regards to signal strength).
Those two processes on Tecno
phones are unusually high as seen
below. In essence, a shocking
amount of battery is being wasted
on those two processes because no
one has bothered to tweak them for
the hardware.
So putting everything into
perspective, maybe Tecno knows it’s
sleeping on its battery game and just
tosses you a power bank to make up
for that and score marketing points
in the process, because frankly, it’s a
lot cheaper to dash out power banks
than invest in R& to optimize an OS
for your hardware. Think about it
this way: With the power bank, you
get two batteries for your Tecno, but
maybe all you should need ideally, is
one.
