MacBook Air Laptop Battery replaced but only lasts 6 hours?

[MarcusBeatitudes]

• MacBook air early 2015 11-inch battery was trash (1000) cycles
• Replaced the battery with this one https://www.amazon.com.au/gp/product/B00WSLYABY/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1
• MacBook battery still trash lasting 6 hours even when l calibrated it. (100% - 0%)
• These are the steps l used to calibrate it: 
• 1) Shutdown, plug in A/C power and wth the computer turned off, charge up to 100%, then keep charging for two more hours.
  2) Reset the SMC (System Management Controller).
  3) Boot up the computer and disable sleep mode in Energy Saver preferences.
  4) Use the Activity Monitor Utility to set up a slow and steady power usage.
  5) Unplug A/C power and leave the computer undisturbed until 0% battery turns off the computer.
  6) Leave without power for 5 hours more to completely discharge.
  7) Plug in A/C power - charge up to 100% and then for two hours, with the computer turned off, as before.
  8) Unplug A/C power, and discharge the battery using the computer more normally but avoid any high energy apps or services.
  9) Plug in A/C power - boot up, Reset Energy Saver settings if necessary, and use as normal.

 

Macbook Battery lasts 6 hours with half brightness running Chrome YouTube videos. Not sure what else to try. Maybe l didn't do the process correctly? So I'll try it again.

Genuinely sounds like low quality cell that cant hold the 100% charge, whats the report on the charge information in the settings?

It says its normal.

Correction: Battery lasts around 6 hours from 100% till 0% (I usually try to use it from 80%-20% which gives around 4 hours) looking at the battery level of last night which l still think is low for a new battery.

Either your poor battery life wasn't due to the battery in the first place (some app hogging resources/crashing and using CPU, system bloat) or that's a crap 3rd party battery.

I don't see any app hogging resources and the battery from amazon seems legit enough unless its really not.

What macos version are you running?

Latest one. Big Sur 11.4

[Kilrah]

Could just be that newer macos versions have become less efficient / well tuned to the older hardware.

You gotta be kidding me. ALRIGHT THEN I"M DOWNGRADING TO CATALINA 

[Kilrah]

If you really want to get down to it I would wipe, clean install big sur, see if it's better, if not install the original el capitan and see. If it's still not better then it's the battery...

The thing is, I already did a clean install as l also installed a new ssd into the system. I'll try to install the original el Capitan.

6 hours with Chrome is shockingly good, actually. 

 

Apple claims that battery at up to 9 hours browsing the web which equates to light Safari use or watching hardware accelerated video with subtitles, annotations, channel logos and everything else turned off. Chrome is super inefficient and consumes more energy than Safari. YouTube is also super inefficient and pretty much screws efficiency with channel logo overlays, annotations and timestamps on the timeline. Said things are outside of the hardware video decoder and slash battery life even when you're in fullscreen.

 

My MacBook Pro 16 is rated at 11 hours and if I fire up a YouTube video in Chrome, the estimate jumps down to like 5.5 hours, same goes for browsing pages. If I start a fullscreen video in QuickTime without subtitles, that estimate jumps to like 12+ hours. Same goes for light browsing on Safari. 

 

TLDR: You're seeing expected behavior.

Interesting. I use Chrome all the time. The thing is, I really hate safari so is their another web browser that has the features of chrome but also has the optimisation of safari? Maybe some extensions might fix the battery life as l watch a lot of YouTube and work on google docs.

Hadn't noticed the Chrome mention, but yeah, forget about getting the quoted battery life with anything but Apple's own Safari they've finely tuned to their OS/hardware...
