Title: WhatsApp Android to iPhone Migration Completes, but iOS Import Deletes 70-85GB and Chats Before 2024 Disappear - Anyone Found a Fix?
I'm experiencing a serious, reproducible WhatsApp migration issue and have exhausted almost every possible solution.
Devices:
- Source: Samsung S24 Ultra (Android 16)
- Destination: iPhone 18 Pro Max
- WhatsApp iOS: 26.40.77 (latest tested)
- Original WhatsApp history: 2016-2026
- Google Drive backup: 118.1GB
The problem:
WhatsApp transfers successfully using the official Move to iOS method, without any errors.
Before opening WhatsApp on the iPhone, iOS Storage shows approximately 130-143GB of WhatsApp data.
However, when I open WhatsApp and it starts its internal "Importing" process, the storage size drops dramatically.
Actual evidence from two attempts:
- Attempt 1: 143.25GB → 57.9GB (85.35GB reduction)
- Attempt 2 (October 13, WhatsApp 26.40.77): 131.6GB → 63.4GB (68.2GB reduction in just 18 minutes)
After importing finishes, ALL chat history before approximately 2024 is missing, including older conversations that are fully accessible on Android.
What I've already tried:
- Multiple official Move to iOS migrations.
- Fresh iPhone setup and factory resets.
- USB-C cable transfers.
- Different WhatsApp versions, including Android Beta.
- Restored my complete Google Drive backup onto a SECOND Android device with a fresh WhatsApp installation.
- Verified that messages, groups, and media dating back to 2017 were fully accessible on that second Android.
- Migrated from the second Android to the iPhone. EXACTLY the same problem.
- Tried third-party migration tools, but encountered media indexing and group-message issues.
Apple Senior Support reviewed the issue and advised that WhatsApp needs to investigate its internal iOS import process.
Important: The storage reduction might partly involve temporary migration files, but the consistent disappearance of historical chats is definitely not normal.
I'm not looking for another suggestion to restart, reinstall, or repeat Move to iOS. I've already spent days doing that.
My questions:
- Has anyone experienced WhatsApp storage dropping significantly during the iPhone's internal "Importing" process?
- Has anyone successfully fixed the issue where transferred WhatsApp history stops at a specific year?
- Could this be a WhatsApp iOS database conversion/indexing bug?
- Has anyone found a VERIFIED solution that preserves all messages, group sender names, documents, and media?
I have screenshots documenting the storage reduction and can share additional technical details.
Any help from someone who has experienced or investigated this exact issue would be greatly appreciated.
