📊 Threads inazidi kupanda kwa spidi, na soon itaipita X/Twitter kwa kuwa na watumiaji wengi ambao wapo active.

Meta imemteua Connor Hayes, Makamu wa Rais wa Bidhaa kwa upande wa Generative AI, kuongoza Threads, akichukua nafasi ya Adam Mosseri ambaye alikuwa Mkuu wa Instagram.

7. Epuka haya ili usiharibu battery calibration:

❌ Kuacha simu ipoteze chaji hadi 0 mara kwa mara
❌ Kuchaji usiku kucha kila siku
❌ Kuweka apps zinazodanganya stats za battery
❌ Kutumia simu kwenye joto kali au apps nzito wakati inachaji

3. Chanzo cha tatizo hili ni nini?

✅ Battery calibration inaweza kuharibika kutokana na:

— Kuacha simu mpaka ifike 0% mara kwa mara
— Kuweka firmware isiyo rasmi (custom ROMs)

6. Je, factory reset husaidia?

Ndiyo, ikiwa tatizo ni la software.
Reset huondoa cache na makosa ya system — huwezesha mfumo wa battery kusoma tena uwezo halisi wa betri.

Lakini ikiwa betri imeharibiwa ki-hardware (kwa mfano imevimba au imechoka), suluhisho ni kubadilisha betri

5. Suluhisho la kiufundi zaidi:

🔧 Kwa simu zilizo-rooted au zenye recovery mode:

— Ingia recovery mode
— Futa battery stats (wipe battery stats)
— Kisha fanya cycle mpya ya charging kama hatua ya juu

⚠️ Tumia njia hii kwa uangalifu si kila simu inaruhusu.

2. Dalili za calibration iliyoharibika:

🔸 Simu inazima ghafla ikiwa na 30-70%
🔸 Ikifungwa tena, inaonyesha bado chaji ipo
🔸 Inacharge haraka isivyo kawaida hadi 100%
🔸 Battery ikishuka hadi kiwango fulani, app huanza lag au freeze

9. Nini cha kufanya kabla ya kununua betri mpya?

✅ Kwanza fanya calibration ya kawaida
✅ Jaribu factory reset
✅ Scan simu yako dhidi ya apps mbaya
✅ Angalia kama battery health imefika chini ya 80% (kwa iPhone unaweza kupitia Settings > Battery > Battery Health)

4. Suluhisho la muda mfupi (Manual Recalibration):

1. Charge simu hadi 100%

2. Itumie hadi ijizime kabisa

3. Iache kwa dakika 30 ikiwa imezimika

4. Icharge tena hadi 100% bila kuitumia kabisa

➡️ Hii husaidia mfumo wa simu kurekebisha makadirio ya battery health.

Tatizo la battery calibration linaonekana dogo lakini lina madhara makubwa:
📉 Simu inazima ghafla
🔋 Ufanisi wa betri unapungua
📱 Inaharibu uzoefu wa mtumiaji

8. Mbona simu mpya pia inapata tatizo hili?

⚠️ Hata simu mpya zinaweza kuathiriwa ikiwa: — Zilitoka kiwandani na calibration mbovu
— Zimewekwa firmware za ajabu (kwenye simu za kichina)
— Zimewekwa apps zenye malware au spyware
